You will certainly be banned if you...

-Create multiple accounts

-Spam the forum (including use of profanity, personal attacks, and persistent off-topic comments)

-Use personal directed profanity in TE chat (if you think something might be profanity, don't use it!)

-Quit a match and resume later with different stats from when you started the match

Keep in mind that you can still be banned for actions that aren’t on this list.
