How about this:
Login to a proxy far away from where you're playing in, change your current password to something totally different than it has been before. Then login to WoW, bot as long as you want.
If you get banned, just log out, log out from the proxy, wait some time and tell Blizzard you were hacked. They should believe you as your IP comes from the other side of the world and your pass was changed before.
Please tell me if you think this works!
