PROOF Blizz can check IP's

[GanjalfTheGreen]

The whole breach of privacy thing means **** all seeing as when you agree to play wow you are accepting that they will be doing all these scans to make sure you're not running 3rd party programs...... so unless you spent days finding a small flaw in blizzards agreement... then there is nothing we can do about it ^.^

hmm if blizz send out a keylogger to spy on your computer you can just go to the police.

we havent accepted anything about they can go into your computer.

They would also be banning university players and others that share internet connects (appartment tennents etc.) For this reason I don't think blizzard would ban IPs
