I got hacked, or phished or something and someone cleaned out all my gold, about 70k worth on that acct, then for some reason they were farming in tempest keep... (I got some epics out of it too...) then they got me banned for abuse of the economy. I filed the straightforward account compromise form (which is hella easy, kudos to blizzard for streamlining this process) and 30 minutes later, i got my account back. Still waiting on the gold taken from the guild bank (they said it will be sent to the guild leader, which is on a different account.)
well i was botting just this morning, and the acct had gotten banned before from botting, so its good news that they don't investigate too deeply when they restore compromised accounts
