I take that back. I'm still suspended. Here's what I wrote to Twitter for an appeal:

I was suspended in January of last year without given a reason, just stating that I had violated Twitter policies without even pointing to any specific policy (because I didn't). I had just posted a sarcastic response to the Twitter team for congratulating itself on censoring people, and then I was censored. Now that Elon Musk owns Twitter, I politely demand that my account be reinstated. Thanks, shitlibs.
