English, lol.
1st of all, depends how you've been banned. WarRock INT only does Account Ban and Hardware Ban. You can't do anything about Account Ban, other than submitting a ticket and hoping for the best. Hardware Ban is a simple fix, System Recovery, or System Restore <-- Last Resort ) will simply fix that.
WarRock is undergoing maintenance as we speak, however.
So people shouldn't be worrying about being banned right now.
