Except the number cited isn’t for social media posts. It’s all arrests under section 127 of the Communications Act 2003 and section 1 of the Malicious Communications Act 1988, which covers far more than social media (as you can probably guess, given social media didn’t even exist in 1988.)
That includes arrests for threatening phonecalls, sharing indecent images (child porn and the like - you lot who bang on about Epstein all the time are meant to be against that, right?) - and not only on social media - stalking and harrasment adjacent offenses like nuisance calling, and a whole host of other offences completely unrelated to social media.
In other words, it’s complete bollocks. And all from one woeful newspaper ‘story’. Congratulations for providing an excellent example of how one right-wing rag with an agenda can confect a story, then have it cited by a load of other ‘sources’ that don’t do anything beyond cutting and pasting the original lie, and then suddenly you’ve made a whole new fact.



Unfortunately, the data doesn’t appear to be collected in a systematic way across the whole country, but one police force - West Yorkshire Police - does have data going back long enough for a trend, at least for the arrests on the Communications Act.
For West Yorkshire Police, the arrests under the Communications Act are pretty much constant from 2008 (around 200) to 2024 (actually a little lower, 152).
Given the changes in social media penetration over that time (things like the iPhone and Twitter barely even existed in 2008,) for the rate of arrests to have remained constant throughout I would suggest strongly indicates that there is a very strong element of “absolutely nothing to do with social media” in those numbers The Times quoted.
The numbers for the Malicious Communications Act are less easy to parse, because they don’t go back far enough, and also they show a massive drop in the last 6 years.
All of this of course could be slightly moot - because in 2023, a new act (the Online Safety Act) was passed which specifically relates to “arresting people for their social media posts” [TM Musk et al].
In 2024, West Yorkshire Police made 5 (five! Count them! Hell, you could invite them all round to your house for dinner) arrests under the OSA.
“Thousands” of people are categorically not being arrested for their social media posts in the UK every year. Or even every decade.
