Kopps and Robbers...
Brian Kopp sold his World of Warcraft guide for a tidy sum on Ebay and elsewhere. Problem was, his product was short on the "guide" and long on the cheats and exploits. Consequently, Blizzard sought to make a symbolic example of this glitch-ganking entrepreneur by threatening a cease-and-desist order aimed at curbing his sales.
According to Cnet, after repeated counter-notices and litigation seeking monetary damages from Kopp, Blizzard's withdrawn it's threats.
The terms of the settlement do not provide for monetary compensation for Kopp, which he had originally sought. Instead, the companies agreed to withdraw their previous take-down notices and to drop their infringement claims. They also said they'd refrain from filing any future take-down notices against the same items Kopp had already disputed through counternotices.
Kopp, for his part, agreed to retain the book's disclaimers about its unofficial nature and said he wouldn't include links or instructions on how to locate "cheats" in the game.
We offer plenty of guides here at Ten Ton Hammer. Guides that provide some fundamentals to build on, that offer hints on how to spend your precious gaming time most effectively, and yea, we give you the occasional spoiler to help you past a tough spot. We differentiate ourselves from Kopp's ilk because we want you to fully experience and enjoy these games while keeping the frustration level to a minimum. Cheating your way to level cap is a cheap thrill compared to the lasting joy you'll get from getting involved with the game's community as your character develops. /rant off
