Quite a while ago somebody shared some post analysis tool that would try to pair up the accounts of multi-account users. Used some cosine distance magic IIRC. Anyway, can’t remember the link, but it seemed to impress folks (I have only one account so wasn’t able to test it myself).

I wouldn’t be surprised if anybody you wanted to do opsec against had a much better version of that tool…

I do sort of wonder where that sort of stuff will go. In one hand, we’re all mostly just shitposting anyway so we don’t really need privacy. On the other, I dunno, we all enjoy being able to explore ideas pseudonymously, right? I wonder if we’ll all end up having to pass our arguments into LLMs to get any sort of pseudonymity in the future.
