Yes, the support system. Since ban discussion is a breach of the forum rules we are not allowed to discuss them anywhere on the forum.
It's part of the players privacy. If they want you to know they will tell you, otherwise it's a lost cause.
Kind of funny when they arent allowed to tell us in the first place though..... If i got banned and i make a post telling everyone, it will get shut down. So your logic is flawed.
