Blizzard lays down the ban hand on 350,000 accounts

Continuing their efforts to "ensure a fair and fun online experience", Blizzard have identified and closed over 350,000 StarCraft and Diablo II accounts. These accounts were found using third-party hacks.

However, the Diablo II accounts that were found for using third-party hacks are not permanently banned. For some reason the accounts are only lockdowned from playing on Battle.net for 30 days. However, should they continue cheating they will be permanently banned from Battle.net.

"As a reminder, we reserve the right to close the accounts and ban the CD keys of players who are caught cheating on Battle.net. Cheating ruins the game experience for legitimate players, and we will not tolerate it," says Blizzard in the official statement.
