The reasons a ban can happen

@E9ine_AC And yet you can do none of the above, and get banned as well, and you're guilty 🙂 I did nothing, wasn't good at the game, and got banned. And each appeal of mine as been denied. It sucks, it's there game, so the best I can state is don't spend any money if you don't want to have it lost.
I'll keep appeal the ban, and am scared to create another new account, since I still don't know why they banned me, and the last couple appeals have been stop asking - we won't unperma ban ya. Be careful, don't even plug in anything like a PS4 controller, or if you end up in a game that is running slow. Quickly quit to avoid being seen as a person on it.
I.e. if you end up in a broken server, they might just ban you thinking you caused it. Especially if it happens more then 2x in a month.

Best bet - only join a team with 1 or 2 other people you know. Don't play randoms. If you get unlucky you can get banned for doing nothing.

good luck!
