I've had three twitter accounts over the last 15 years and all of them were permanently suspended for calling people cunts within the last two years. Well, Tory MPs and Nigel Farage, so not really people.
Anyway, I've never been able to terminate those accounts with the suspensions in place. Found out I can appeal the suspensions and let Twitter know I'm appealing just so that I can close the accounts. They've removed the suspensions on all three accounts citing that they had made a mistake in perma-banning the accounts in the first place.
Weird how they didn't come to that conclusion when I appealed at the time they suspended the accounts.
Anyway, managed to terminate all three of them. I'll see how BlueSky fares before signing up.
