I got suspended for posting the following, in response to a story about a leftist supergluing their hand to a painting in a museum, so their T-shirt that said "End Oil Now" (I think that was the message) would get publicity:
Just cut their hand off with a chainsaw; problem solved (but someone will eventually need to clean off the rotting hand)
Pretty obvious it is a joke, but either twitter has AI that can't recognize a joke, or people who can't.
It seems that any post that has any violent act, or calls someone a mean name, will get you suspended.
