I bought an account from them and it was closed a few days after I bought it for 3rd party programs.

***Notice of Account Closure***

Account Name: XXX
Offense: Unapproved Third Party Software

A third party program is any file or program that is not a part of the World of
Warcraft software, but is used to gain an advantage in the game, such as
increasing your movement speed or teleporting from one place to another beyond
what is allowed by game design. It also includes any programs that obtain
information from the game that is not normally available to the regular player
or that transmit or modify any of the game files. Normally, this classification
does not include UI modifications, except those UIs that require an external
application to function.

Any external applications that are used in conjunction with World of Warcraft
can cause quite a few unwanted side effects. Some of the major possible results
of the use of third party programs can be instability of the game to the point
that a player "crashes" from the game quite often. External programs can also be
used to transmit viruses, spyware, and other unwanted programs into a player's
computer. Third party programs can also be used to obtain information from the
player's computer, such as account, password, and personal information.

If a player is found to have used such a program, he/she may:

* Be temporarily suspended from the game
* Have further action taken, up to and including account closure, based on
the intent of the program

Access to the World of Warcraft account xxx, and any World of
Warcraft account associated with the payment information you have provided, has
been permanently disabled. The account has been identified as having used
unauthorized game modifications and thus is in violation of the World of
Warcraft Terms of Use. The recurring subscription on the account has been
disabled to prevent further charges.

Please review the World of Warcraft Terms of Use at
http://www.worldofwarcraft.com/legal/termsofuse.html, which you accepted when
you installed World of Warcraft and established the account(s). Section 2,
Paragraph C details the limitations of game play modifications and use of any
third-party or “packet sniffing” software. In addition, Section 3, Paragraph C,
parts iii and iv restrict the use of any hack, scripting or macroing software
which obtains information from World of Warcraft to gain a competitive advantage
over other players.

Furthermore, any activities not intended by game design which affect the
economy, the client, player characters or the world itself have a tremendous
negative impact on the potential enjoyment for all players. The effects of
these activities take many forms including a bloated game economy, server
instability, and allowing unauthorized access to accounts, computers, and player
data.

As a result, the account(s) will no longer be accessible and will not be
reopened under any circumstances.

Any disputes or questions concerning this account action can only be addressed
by the World of Warcraft Account Administration department. To learn more about

Thank you for your understanding in this matter and respecting our position and
all statutes within the World of Warcraft Terms of Use.

I tried to contact them and got no answer and their online support could not help me. They told me to contact the owner, I've filed a paypal claim and lost because paypal does not cover virtual goods.

They stole 599!

I wish I googled them first but now it's to late. I hope you find this post before they do the same thing to you.
