I had it happen with my WoW collector’s edition account (except they never notified me, or anyway I didn’t get any notification) and that account remains banned to this day. Nothing I tried got them to budge an iota or even tell me why they were so adamant without ever trying to confirm that I wasn’t in control at the time. I’m still angry about it to this day. (This was back in like 2005 or 2006, maybe? Burning Crusade was about to come out, hence my attempt to resub that resulted in discovering the ban.)
