Further you can say dumb shit on twitter/youtube/facebook as well, there's just certain lines you're not allowed to cross. My understanding is you don't get instantly banned by tweeting 'arrrarggghg!! MAGA"!, but if you tweet 'arrrrrghgggh! Kill the ____" you get a temp-ban and a warning. If you break the rules three times you get a perma-ban.

If you lack the self-control to follow the rules three times, then you can't complain when you get banned.
