I think this is less meant for long term torrent sharing and more meant for people to use the BitTorrent protocol to share stuff with each other. They’re only sharing it with a small group of people.
It’s not like a traditional private tracker where it’s a group of people, or a public one where it’s the whole world.
Torrents-CSV looks really good. It would be great if they had a search plugin for that honestly. It’s just nice to be able to initiate downloads from Qbittorent itself.
