Edit: obligatory explanation (thanks mods for squaring me away)…

What you see via the UI isn’t “all that exists”. Unlike Reddit, where everything is a black box, there are a lot more eyeballs who can see “under the hood”. Any instance admin, proper or rogue, gets a ton of information that users won’t normally see. The attached example demonstrates that while users will only see upvote/downvote tallies, admins can see who actually performed those actions.

Edit: To clarify, not just YOUR instance admin gets this info. This is ANY instance admin across the Fediverse.

    To anyone surprised at this: welcome to the fediverse, please treat everyhing you do or say as public.

    The way to achieve privacy around here is by following the long forgotten arts of the old internet before Facebook was a thing: use a Nick name and don't tell strangers on the internet your real identity.

    Your home instance will act as a proxy and only they have access to your email and IP address. That does stay private.

    So, as long as you trust your home instance to not leak or disclose your connection or sign up data (which would be illegal in EU countries), just sign up with an alias.

    A very positive aspects of this is that it should allow us to detect voting manipulation by correlating the activity of certain potentially malicious actors. If Lemmy instances take vote manipulation seriously and do their best to block bots this has the chance to make Lemmy / Kbin much more transparent and credible than Reddit ever was.

      I whole heartedly agree with this perspective.

      Additionally, and this is an unpopular opinion, but trying to maintain a Nick or online identity over many years is folly. You end up with a huge repository of personal information, increasing the risk that it can be connected to you personally.

      No, an alias will only give you pseudo-anonymity. Even trivial analysis like counting which words occur together frequently in your writings can reveal with very good accuracy any other alt of you, so the available information of you is basically everything you have shared online with enough accompanying self-written text.

        Also, it’s not just about privacy, it’s about retaliation. It will be the easiest thing in the world for people to put together bots that will track the downvotes on every post they make and automate adding those people to block lists. Suddenly a whole fleet of alts is invisible to the people that would disagree with them.

      Your home instance will act as a proxy and only they have access to your email and IP address.

      Your home image typically doesn’t proxy image loading, those are hotlinked to the Lemmy server that the image was uploaded to. So your IP address and browser string are going to other Lemmy servers.

    To illustrate op’s point I’m going to spin up an instance, federate with everyone, and not tell anyone what that instance is.

    Then I’m going to feed all that data into my new website, called Open Lemmy Stats, where anyone can query the user data ive accumulated. The homepage will be ripe with insights, leaderboards and all kinds of data on prolific users.

    Additionally, I’ll display a snapshot/profile of a random user by feeding that users data to GPT4 to make inferences about the user’s political affiliations and display the results.

    Worst of all, I’m not going to out my instance for everyone to know it as the one to defederate. In fact I’m spinning up a few instances that will host innocuous communities that I plan to mod and support to give my instances cover for their true purpose: redundant fediverse datastreams for my site, Open Lemmy Stats.

    I’ll also have a store where anyone can buy my collected fediverse data for a handsome sum.

    Just kidding I’m not doing any of this. But someone absolutely will or already is.

      I think your comment clearly illustrates what might go wrong with it. If they need this data for sorting or something else absolutely, then I would be happy if they just hashed the usernames/instances or used some other form of UID.

      And just think how much data you can gather by sending out puppet accounts on various instances, accounts that will serve only to publicly state an opinion, such as “I support this candidate”, so the data on the people who upvote it can be harvested and categorized more easily. There is so much data harvesting potential here with a little imagination, and with a little more, a lot of ways to use that data to influence the way average users engage with the fediverse.

      That site would also be a great advertisement for Lemmy. Come here to our decentralized platform, where you can vote…but you better not, lest you end up on the site. What social network wouldn’t grow when users are peer pressured into not using one of it’s basic underlying mechanics that makes the whole thing work?

        Lemmy is not a decentralized platform. It’s a federated one. Lemmy is very much centralized.

      They will know the user but not the person in real life. Even if you know that my user is more conservative on some points or more liberal on others, how can you use that for nefarious action ? Unless you know where I live and who I am, the data is useless.

      People need to be aware that sharing your personal information on the internet is never a good idea.

        It’s very difficult to both A) have meaningful conversations in a public space, and B) conceal your identity from a dedicated adversary. Once a person has a long post history, it’s likely that an observer could narrow down their identity to a very small group, if not a single person. Every post you make reveals something.

        Even if you don’t ever explicitly state it, your age range and gender can likely be guessed with high probability by your writing style and/or little tidbits of info you leak without thinking about it. Same for political leanings. You might casually mention the brand of car you drive, or your favorite foods, or just reference something you experienced as a child that is not universal. All of these things leak information, and while each one seems insignificant, in aggregate they can tell a detailed story. Just knowing that you’re a Canadian who speaks both French and English eliminates about 99.8% of the world’s population as possibilities.

        Back on Reddit I used to create fresh accounts all the time, but then I’d go and join the same subs, post with the same writing style, and generally express the same worldview. If anybody cared, had a good grasp of statistics, bothered to collect the data, and put in a stupid amount of time to it, they could likely match all of my accounts together. I was never too worried about this because…well I just didn’t care. But I did have a cyberstalker at one point and it made me think.

        I wouldn’t be shocked if someone could match me to one or more of my Reddit accounts just from this one comment, tbh. I’m leaking information here like a sieve! Not many people have the skills to do that, and the few who do are unlikely to give a rat’s ass about me. HOWEVER, as AI becomes more advanced, anyone with computer literacy will be able to do analysis in minutes that might currently take an expert days or weeks.

          You’re looking at this from the wrong point of view. The fediverse is not just lemmy: Threads, Tumblr, even BlueSky (albeit with their own protocol, but anyone could just modify their fediverse enabled app to convert their data to be applicable to BlueSky’s protocol) are quickly setting the stage for a new norm. The more websites integrate the fediverse into their stack, the more data outside the immediate sphere of influence of these major corporations can be harvested. To what ends they’ll use it, I don’t know – but I don’t trust them with it.

      Honestly, why not? The data is already being recorded. At least this way it’s public and the rest of us get to interact with it. It might even scare a few people into paying attention to the information that they disclose about themselves and increase their digital hygiene.

    Reading these comments, seeing so many excuses, sarcastic responses, and handwaving, makes me realize a great deal of users really need to develop some imagination.

    This is not about privacy. It’s about data that can easily be used for targeting and profiling users, and how that creates countless avenues for targeted harassment and wide scale retaliation. It’s about all of the innumerable ways public vote information can and will be abused to manipulate scoring across the site with targeted/automated shadow banning and shared blocklists. Raise your hand if you trust every single admin to never abuse such a tool to curate the outward appearance of an instance to fit a narrative.

    For a different example: I could say something about how great Nazis are right now, and have a bot programmed to read every single person that downvoted me, add those names to a shared blocklist, and viola, I’ve made myself and all my alts invisible to the people that would challenge me on a massive scale.

    I promise you this is going to be a big issue as tools for this site get more sophisticated over time.

      alternatively, if votes were private, you could spin up a bot network to mass upvote your comment; making it far more influential as most people are more inclined to believe statements they think others also feel. thankfully, votes are open, so you can’t

      While I agree this shouldn’t be so publicly accessible, I’m curious about the possible benefits of limited sharing between instances to give spam/bot detection tool’s more power.

      Users on A vote on a post on B. The admins from A and B can see the fine details of who did what, but the admins of C (and all of the general users regardless of instance) just see totals of up/down votes.

        Ideally, detecting bots should be up to the Admins. They should have access to the vote information, and they can share the tools with other admins to detect it. But the average user should not have unrestricted access to this data.

            Let me be a little more clear, the Admins of your account’s particular instance should be the only ones that have access to your votes.

            Now the question remains about when your account posts/comments into a different instance, who should have access to those votes? Perhaps your instance has a way of obfuscating the votes of any user coming from your instance, or else only the admins of the community that you’re posting into will have access to your votes?

            The problem really comes down to how we avoid the problem with duplicating votes. Currently this is easy as each vote is public so every instance can verify the correct vote count. But implementing either of the solutions above will need a way to verify the correct number of votes.

            To top it off you would also need a way to detect if a malicious instance had come along and started lying about how many votes had been cast.

            One thing we can look at under the hood would be how cryptocurrency works as they have solved both the problem of duplicate values as well as the ability to trust those values being sent. All of the code is free and open source so we can pick out the parts that we need and reuse it. (And no, I’m not telling people to go out and buy crypto).

            Z Cash would be a particularly good one to look at as it ensures a “zero knowledge” (or “zero trust”) method of sending the values across “nodes” (or in our case “instances”). Using this, who is voting on what would be hidden, but we could ensure that the values are correct.

            Additionally you could probably throw out the second hashing algorithm altogether and just keep the Blake2b hashing algorithm as this one is far more efficient and quick to compute (and that second algorithm was mostly thrown in to prevent people with specialized hardware from being able to come in and beat anyone else running on just a GPU/CPU). https://github.com/zcash/zcash

            However, using this particular method would make it so that not even the instance admins would be able to view the details of anyone’s votes (which may be a good thing after all if we decide that any random instance admin is not to be trusted).

      I agree with you about harassment issues, and the importance of controlling the transfer of admin-level data between instances, but for your last scenario, doesn’t blocking only apply to users who are logged in? Assuming your hypothetical tankies and Nazis were actually posting as well as blocking, it would be easy to find them just by logging out, and there are a lot of ways to get them banned or otherwise counteract their activities that don’t require someone to interact directly with them while logged in. The case you’re describing is not the kind of situation where the most important action is to argue with them. Arguing with extremists usually just validates their delusions, and encourages them to keep doing what they’re doing.

    Not to sound harsh or anything, but those of you saying that it’s okay that all this data is public are insane. This completely goes against the entire philosophy of the Fediverse and FOSS in general. The reason we all are fleeing from Big Tech is because they collect so much data on us. At least, they keep it hidden from public view. This is a major issue in my opinion, and needs to be addressed ASAP before we can claim to have superior platforms on the Fediverse. Why can’t this data at least be encrypted?

      Agreed, I am incredibly confused by what seems to be the majority reaction to this.

      I’ve never been particularly involved with the FOSS community, though I do use a few FOSS apps and generally appreciate their view on what FOSS means. I also strongly appreciate data privacy, and it was my observation that the FOSS community was (generally) relatively the same way. So to see this reaction is very surprising. It’s quite literally the same terrible argument of “Why fear it if you have nothing to hide” used against multiple data privacy concerns throughout the years.

      I think the worst are the bad faith “But Reddit…!” arguments. For one, we’re not on Reddit anymore, this is about Lemmy’s issues that can be corrected. And for two, whilst Reddit potentially outsourcing that data to the highest bidder is far from ideal, at the very least the data wasn’t outright PUBLIC to anyone who wishes to set up a simple server.

        Exactly. When data like that is public, I can guarantee you 10000% that Big Tech and governments are harvesting ALL of it as we speak. If this issue is not resolved and TRUE privacy is not implemented sooner rather than later, Lemmy will not succeed in the Fediverse, period.

          If you want privacy you need to use an encrypted chat. You can’t have privacy in a public space. That is like stand in the middle of a market place, screaming out your thoughts and then being upset that someone writes them down. It sure would be nice if our data wasn’t harvested, but that is not the world we live in. So if you want to say something in private you need to choose a private platform. Otherwise assume that Big Tech and World Governments are listening.

            There’s a huge difference between what I choose to put out in public vs. data that’s being collected on me just by browsing the site. Saying “it’s just the world we live in” is just an excuse to ignore the real issues. It is more crucial now than ever that we create a system that’s by and for the people, not Big Tech and governments.

              It seems that what you would like is something like 4chan, where the post will get deleted if it’s not popular. But even that, there is no way to prevent data harvesting. If it’s public, then it is public. There is nothing you can do about it. Encryption wouldn’t solve anything either because you want this data to be read by everyone so you cannot really encrypt it.

              The fediverse is kind of the same as a public room where anyone can come in and just listen, take note, see who is talking and respond in the same way.

              This is the point of social media. If you don’t want to participate in it because of privacy, then don’t and just lurk (or listen) like most people do.

              By definition, if it’s on the internet, it’s pretty much there forever. People need to be careful on what they share on the public space, in the same way you would when talking to a big crowd. You are not talking with your friends here, you are talking to the world. If you are any privacy, you just cannot have it here. That’s impossible.

        You say these issues can be corrected but I am not sure they can. ActivityPub is a protocol managed by the W3C. So to have different behavior You’d have to change the specification there. That is possible but it will take some time. Still you’d need a way to make votes not bound to a user and still hard to spoof. That sounds hard. Apart from that upvotes and downvotes are not really the most interesting datapoints you can gather. You can still collect posts. These can’t be obfuscated. There is simply no way to have an open network where you can share data between servers where you can make sure that no one harvests the data. It is simply not possible. As soon as it is public it is public. This has nothing to do with FOSS. If you have a solution you can implement it. That is what it means. If you have one then go ahead.

          Then they should do so, these issues need to be fixed ASAP.

          Still you’d need a way to make votes not bound to a user and still hard to spoof.

          Obfuscating user IDs via a hash or something would seem like the way to make it work. I’m not a professional programmer, I only know a little bit of python, so I have no idea if I’m talking nonsense on that front. And whilst still not an ideal solution, but sharing non-private votes with your own instance admin and have them share only the total vote count with other instances is another solution. That way you need only trust your instance admin, which is choosable and can also be yourself.

          That is what it means. If you have one then go ahead.

          Putting the onus on me is a shitty thing to do. I’m not the one running this site in any capacity, but this is an issue that many users are unhappy with. If the issue with the site won’t or even can’t be fixed, then I will simply not use the site. I don’t know how many people feel the same on that front, but I’d imagine there’s quite a few.

            Maybe that’s what you should do. But don’t do it as a protest. Do it because you don’t want to share that data publicly.

            The entire point of social media is sharing things publicly. If you’re worried about people collecting that data, then you shouldn’t have put it in public.

            There aren’t good ways to keep a public secret. That’s inherent to how information works and not a failing of ActivityPub. It’s the same reason media will never stop being pirated. If I can see/hear it, I can repeat it.

              But don’t do it as a protest. Do it because you don’t want to share that data publicly.

              I mean yeah, that’s what I’d do it for. It’s a suggestion for the site and it’s a sentiment that seems to be shared by several people here, but it ultimately falls down to me to decide whether or not I want to continue using it, much the same as with my usage of Reddit.

              If you’re worried about people collecting that data, then you shouldn’t have put it in public.

              Voting is a core functionality of the site. It’s something I don’t think should be public as it puts more emphasis on what content I interact with in what is now apparently a public manner. If you want to debate that a mere vote is something I shouldn’t put in public, then fine, you do you. But for me, it defeats half the point of me even having an account here. What one comments on are often an incredibly small portion of what one actually votes on simply by ease of voting.

              And I know I said “But Reddit…!” is a bad argument earlier, but even so, I’d like to say that even Reddit’s voting is not publicly accessible (as in not accessible by other users, even if Reddit almost certainly collects and sells such data), so clearly there should be ways to do it. If ActivityPub requires public voting and the people who have the ability to change it are unwilling or even unable to do so, then fair enough. But equally, I will refrain from contributing to such a site, which seems like a bit of a shame when it seems close to ideal otherwise.

                clearly there should be ways to do it

                Your votes on Reddit are public to Reddit admins. On Lemmy anyone can be an admin.

                Giving vote totals without names makes the system ripe for fraud and abuse. In real life votes the decision to make votes public or private is a major one. In a system like Lemmy, the problems with private votes are exaggerated, and the problems with public votes are much smaller. Your Lemmy name shouldn’t be tied to your real name. It’s unlikely anyone is going to coerce your vote like they might coerce your political vote.

                If you’re concerned about anonymity, maybe use more than one name or a different name so that your account isn’t so easily tied back to you.

                The purpose behind having votes be more public is to have some kind of reputation behind those votes. It’s still possible to shill, but it requires more depth and and effort, and the shills may still be discovered if there are too many.

            Putting the onus on me is a shitty thing to do

            You are the person who has a problem with that and you mentioned FOSS. It is easy to complain. FOSS gives you the tools to change things. But you have to put in the work. You are the one putting the burden the change something to your liking on others instead of doing to yourself.

            Obfuscating user IDs via a hash or something would seem like the way to make it work. I’m not a coder, so I have no idea if I’m talking nonsense on that front. And whilst still not an ideal solution, but sharing non-private votes with your own instance admin and have them share only the total vote count with other instances is another solution. That way you need only trust your instance admin, which is choosable and can also be yourself.

            Both of your ideas are not compatible with ActivityPub as far is I can see. So you first need to change the specification and then make everyone adopt the specification. Before that any change would make your software incompatible with the rest of fediverse which is counter the idea.

            And all of that because people could be mad about a downvote. I am an instance admin. I was downvoted before. I never even thought about looking up who downvoted me. I know people are different but to be honest if someone looks it up and harasses you then you block them. And I really can’t imagine that your vote on a post with a pseudonym is really a very useful datapoint for anyone.

            I agree that these things have to be communicated better but I don’t even know how we would make people aware of this. No one reads disclaimers.

      I don’t think it’s possible to encrypt the data.

      Say we have a rogue user that sends to the server multiple upvote requests for the same comment, how can the server reject the subsequent requests? After all, we can’t let a user upvote a post or comment multiple times.

      If that data is encrypted, the server cannot tell whether the user has upvoted a comment before.

        Well, I am not a developer in this field, so I don’t know what’s possible, and what’s not. All I know is that this needs to be fixed one way or another, or this whole platform will fail. If our information is all available publicly, we will be better off just using Facebook/Reddit/Twitter - at least these platforms don’t leave our data out in public view. We need to stop saying what’s not possible, and instead talk about what is possible.

          Maybe there is a way to keep you votes hidden but there sure is no way to keep your posts hidden. The whole point of federation is to distribute your post to the other instances. You want eat your cake and have it too. You want to post publicly but stay in control of the message. You are not better off using BigTech because there someone can scrape your data as well. And you don’t even know to how many parties your data is sent without your knowledge. There is no privacy in social media.

        There might be possible technical solutions to this using hashing. Hashing is like encryption in that the original cannot be extracted, but the hashed result is unique.

        For example, a solution would be to have a VOTES table with an indexed column that is a hash of a combination of the user ID, post ID, (and perhaps another “salt”, not sure). When a vote is made, the VOTES table is checked that the record (vote) does not already exist, gets an insert, and then a COUNTER is triggered for the actual vote count. (COUNTER is a db command that simply updates a counter). The hash would prevent multiple votes from the same user (as the salted hash is unique), and it would also prevent identifying who the user is from the table.

        Yeah, I had a good natured discussion with a Lemmy user on feddit.uk the other day where they were still inexplicably downvoting my responses each time, despite us both being polite and constructive.

        It made me realise that a) they use the downvote button quite differently to how I use it and b) they probably didn’t know that I, as a kbinaut, could literally see they were the one downvoting.

      One thing I really like is that it makes it easy to identify users to block. If there’s a post stating that “Nazis are bad” and it has ten downvotes, it’s very easy to use that to block future content from trolls and people I’m not interested in hearing from.

        Yeah, and guess what? They can do that to you.

        Effectively, every single person can use a bot that will automate the blocking of any user that ever downvotes them ever.

        Like if I made a post that says I like Nazis, and then waited for the downvotes to pour in. Add every single one of those names to a block list, share that block list with all of my alts and all of my friends, and suddenly you have a whole army of Nazi sympathizers that are invisible to the users that would downvote them.

        These hand waving excuses about votes being public are really lacking imagination. This is extremely abusable information, and cursory tools can will be put together to make abusing them simple.

          I think there are some problems about voting being public. I don’t think this is one of them.

          I don’t mind people blocking me, and if I don’t appreciate the type of content people provide I’ll block them liberally. It’s not necessarily anything personal, I’m just cirating my experience.

          Furthermore, I strive to be on instances where nazi sympathisers would be banned, and where instances tolerating them would be defederated. The only issue is identifying and weeding out troll accounts.

    There is a fundamental misunderstanding here.

    Our data has never been ‘invisible’… We’ve just trusted that places like Reddit and their staff will do the right thing. That’s literally how it already works.

    If you sign up for Reddit, Reddit staff can see your posts and votes if they want to.

    If you sign up for a private forum the admin there can also see database contents.

    One way encryption is not possible without stopping functionality… If data about you was encrypted then posts you make couldn’t be displayed. If you include a means to decrypt then there was no point encrypting anyway.

    This is how it’s always been, and Lemmy doesn’t change this status quo much.

    A faceless corporation that has had access to your data is just replaced by a variety of admins distributed across instances.

    This isn’t a good or bad thing, the potential for abuse does exist, but when we have literally made agreements with places like Reddit that they can use and sell our data… then what difference does it make it an admin takes a peek?

    It wouldn’t be great… but nothing is perfect.

    It’s still worth working on however, to see if a better solution can be found, but at this time I’d say just be aware that it is possible that your data can be seen and understand the only safeguard against that if you need to communicate something private would be to use direct messaging with end to end encryption.

      Ah, the old Reddit Lemmy switcharoo.

      You are probably seeing two very different vocal minorities, and conflating the two.

      Also, there’s a very clear difference in expectations between posting/commenting and upvoting. I blame the UI. We naturally expect public actions to be easily visible. The lack of universal accessibilty to the public data makes people unaware that the data is public. Lemmy UIs, including apps, need to make this information (a list of upvoting users) universally publicly accessible before people will change their expectations.

        On the contrary, I’m not conflating two specifics. I’m speaking in general terms about the demonstrable public perception (read: billions of social media users who happily hand over their data vs. the palpable unease over data publication in all walks of tech discussion) and how it is innately hypocritical.

        It is perfectly normal and useful to discuss societal contradictions. For example: “We hate school shootings, but we do fuck-all to stop them from occurring.” That statement does not conflate two different vocal minorities, it purports to accurately describe the generalized societal contradiction at hand.

        The rest of your post is completely off-topic.

      Yes.

      Just muddling around I’ve built queries that: (a) list all of my post & comments, everybody who voted on them, and their votes (b) tally how many times specific users have upvoted or downvoted me. © identifies the most prolific voters across the Fediverse and the communities they are voting in (d) identifies users with the same username or display name across all instances and correlates the activities across those accounts.

      These are all for the sake of learning and are innocuos the way I’m using them. It is plain to see that someone with skills and an agenda could make more out of it than I have.

        I can’t just spin up a website and automatically get that info from other websites, but I can spin up a lemmy instance and get that info from everyone it’s federated with.

          I agree, someone has to store and maintain your data, but giving all instances access to it is a risk that could be avoided

    Back in my day everyone knew that once you put something on the internet it’s there forever to be seen by all. Has everyone already forgotten this? This is nothing new and in fact the way it’s always been! Now get off my lawn!

    How often are we going to see this postage? I think this is the third time I’ve seen it at least

    Well, yeah, it’s put on the database.

    It’s the only way to avoid double voting from the same account or to remove the reverse vote if one changes one’s mind and votes the other way.

    Did you think that it was any different on Reddit and that no random employee with access to their database could run a similar SQL query with a couple of joins and end up with nicknames, e-mails and IP addresses?!

    Do you know who are the Reddit employees with access to their database or a copy of it? Have you had a chance to vet them? I don’t think so.

    At least here it’s a bit more transparent.

    The only shocking thing in this is that anybody is shocked by it.

      Another way to be more private is to only federate upvote/downvote count, instead of the detail of the upvote/downvote. This is not only lighter but more private. When the count needs to be updated just broadcast the new upvote count.

      But I see why they want to do it the current way, as it is more aligned with activitypub protocol, and allow other platform like mastodon to participate without problems.

      I cannot think of much problem in implementing a “hidden upvote system” in activitypub. Basically, it will work like this:

      • user on instance A upvotes a post in instance B: instance A tells instance B the user upvoted the post, but not anyone else.
      • instance C trying to fetch a post from instance B: B will only communicate the upvote/downvote count, but not the detail
        • if instance C is not a threadiverse instance (like mastodon) it will show “xx number of upvote from B is hidden.”

        Wouldn’t it be easy to lie though? Instance B could report 1000 upvotes to Instance C and Instance C would have no way of verifying that. An instance could boost its own numbers pretty easily, pushing agendas to the front page.

        The transparency allows for accountability. It would be pretty easy to detect an instance making up user upvotes versus a “just trust this number” system.
