Q u o t e: Read about restrictions here: http://forums.battle.net/thread.html?topicId=10972137363&sid=3000
normally they last up to 72 hours. We are unable to determine the specific cause of the restriction but the cause is one listed in that thread.
Unable to determine cause? Wow that's great turns out I can't play Warcraft 3 now either i mean WTF? I don't cheat and don't do any of the things listed on the thread you posted whats to stop this from happening again? I don't want to play a game just to be banned and unable to play half the time for no reason.
Edit: Reason for ban would help so i can avoid in future.
