An anonymous reader writes with this excerpt from Rock, Paper, Shotgun: "Blizzard have taken the extremely peculiar decision to ban players from playing StarCraft II for using cheats in the single-player game. This meant that, despite cheating no one but themselves, they were locked out of playing the single-player game. Which is clearly bonkers. But it's not enough for the developer. Blizzard's lawyers are now setting out to sue those who create cheats. Gamespot reports that the megolithic company is chasing after three developers of hacks for 'destroying' their online game. It definitely will be in violation of the end user agreement, so there's a case. However, it's a certain element of their claim that stands out for attention. They're claiming using the hacks causes people to infringe copyright: 'When users of the Hacks download, install, and use the Hacks, they copy StarCraft II copyrighted content into their computer's RAM in excess of the scope of their limited license, as set forth in the EULA and ToU, and create derivative works of StarCraft II.'" Blizzard used similar reasoning in their successful lawsuit against the creators of a World of Warcraft bot.
