Where to report illegal servers?

Let's clear this up. ;)

From our Terms of Use (http://www.worldofwarcraft.com/legal/termsofuse.html):

Q u o t e:
B. Only Blizzard Entertainment or its licensees have the right to host World of Warcraft! Accordingly, you may not host, provide matchmaking services for, or intercept, emulate or redirect the communication protocols used by Blizzard Entertainment as part of World of Warcraft, regardless of the method used to do so. Such prohibited methods may include, but are not limited to, protocol emulation, reverse engineering, modifying World of Warcraft, adding components to World of Warcraft, or using a utility program to host World of Warcraft.

Now concerning where to report information concerning 'emulated servers' you can e-mail [email protected] with all relevant information. Including the name of the server, and any affiliated websites.
