Whelp, that didn’t take long. Over 5,000 players have been banned for “cheating and/or using hack programs while playing.” Hey, it’s not our fault we can’t stay competitive against the Koreans!
Blizzard took the action, it said, because cheating not only is "undermining the spirit of fair competition," but also because the company claims that the use of hack programs can hamper the performance and stability of Battle.net.
