Blizzard has revealed that it has closed over 350,000 StarCraft and Diablo II accounts which were found to be using third-party hacks.
The company further revealed that the Diablo II CD keys associated with the closed accounts are now barred from playing on Battle.net for 30 days and warned that repeat offenders face a permanent ban.
"We reserve the right to close the accounts and ban the CD keys of players who are caught cheating on Battle.net," the developer said in a statement.
"Cheating ruins the game experience for legitimate players, and we will not tolerate it."
