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.
