I left twitter for good. I'm tempted sometimes to rejoin just to contact some people but then I remember it would only be drowned out by AI antagonobots. I'd rather wait for people to leave, and if they don't that's on them for committing their time to part of the problem, or for twitter to decentralize and become part of the internet ecosystem rather than a tool of woke monied interests.
I deleted my account a few months ago unrelated to the Elon thing. Part of that was me not curating my feed better (like I have on Reddit) but another part of it was me just wanting to ditch an unproductive time sink.
A while ago, I posted something that the Twitter algorithm didn't like (nothing objectionable, just nonsense that happened to match their filters). They locked my account and demanded a number (I had created my account before 2FA was mandatory). Since I refuse to give them a phone number, my Twitter account has remained locked ever since.
When things calm down a bit, I'll check if the lock has been removed. I am mostly interested in contacting a few people to tell them where they can reach me. Beyond that, I won't use Twitter ever again. It is a total waste of time. Over 99% noise, and the 1% signal is very weak.
