Ok first of all, I didn't make this, so credits goes to whoever made it, it worked for me and my friends so I thought it would be a good idea to share it here.
[WoW Exploit] Unban your account!
Call up Blizzard and explain to them that you were on vacation, and someone from the lan-center that you go to
(Because they will probably do an IP check, this way they won't think anything of it) has hacked your account.
Blizzard will then look into your account, ask you for some personal information such as a credit card number and what-not,
and they will then most likely unban your account. As long as you pretend that you were hacked, they will go to change your password
once they have confirmed that you are the owner of the account and also un-ban you :)
This is pretty much guaranteed to work the first time you try it, and possibly the second... But if you try this any more it probably won't work.
Once again I didn't make this so credits goes to whoever wrote it.
