Is there a way to unban an account from a game which has already been banned?? Is there a script or something i can do to unban the account?? I have friends who have been banned and need help too to get their accounts back... If there is a way pls can anyone help me? Is there some tutorial in how to do it? I looked in game guardian forum and i have seen ppl doing script to bypass ban and getting accounts back who were already banned
