Twitter have forcibly taken over people's accounts before. I forget who it was that was affected, but in late 2019 I think it was, some conservative account started posting shit that was completely out of character for them, then the account got immediately banned. It was later revealed that a "rogue" twitter employee hijacked the account and made the posts that got the account banned. IDK if the dude ever got his account back. Sorry I don't have anything any more concrete than that. It was a while ago, and I have no idea how to go about looking something like that up.
