I can still see them on the other instances they subscribe to usually. When I have seen bans the accounts have mostly looked like bots, and got booted for looking like one. The others I have seen have people with violent, or bald faced bigotry. I am sure there are people that got booted unfairly, because people are running the show, and people aren’t great for this sort of thing. However, a standard practice of banning people from the instance for talking shit on Ukraine, or Israel, is not a thing.
