Blizzard announced that it has suspended about 350,000 Battle.net users that used various hacks and cheats in StarCraft and Diablo II. They're not alone, though, as another 7,700 Warcraft III accounts will soon join them in exile.
Blizzard explains this move as an effort to make sure that their players keep having fair and fun experience while playing online, and adds that such bad behavior will simply not be tolerated.
Although these accounts won't be able to access Battle.net for 30 days, Blizzard plans to permanently ban and close accounts of users who think these are just feeble and empty threats and keep on with cheating.
