Greetings,
Thank you for your follow-up email regarding the account WoW1. This account was closed after evidence was produced indicating one or more characters on the account were found to be using an unauthorized cheat program. These programs provide character benefits that are not achievable in the World of Warcraft through normal means. Such benefits include, but are not limited to, character automation (also known as "botting"), increased speed, teleportation, or running through walls/boundaries. These types of programs offer an unfair advantage over other players and supersede the intended limits of the game.

As a result of this determination and the harmful nature of unauthorized programs on the game environment, the action taken against this account will not be reversed. Please understand that we do not reach this decision lightly. This action has been taken in accordance with our Terms of Use (http://www.worldofwarcraft.com/legal/termsofuse.html).
In addition, you are responsible for any unauthorized cheat software found to be running in conjunction with World of Warcraft, regardless of the location and ownership of the computer used to log into the service. Please remember to keep your login information confidential. Any account that is registered to your name may not be shared with anyone except for one minor of whom you are a parent or guardian. The security of your account rests with you.
As a reminder, only the Account Administration department can address disputes or questions about this account action. To learn more about how we are able to assist you, please visit us at http://us.blizzard.com/support/article/21505. We apologize for any inconvenience this may have caused and hope we have addressed any concerns you may have had. Please let us know if we can be of further assistance to you.
