Blizzard, the company behind the Warcraft and Diablo franchises, does not screw around when it swings the banhammer, booting 320,000 online accounts tonight from some of its most popular games.

"We've recently banned over 320,000 Warcraft III and Diablo II accounts that were found to be violating the Terms of Use", a statement on the company's forums reads. "If this is a first offense, the CD key associated with the banned account will be suspended for 30 days, while repeat offenders will see their keys banned permanently. All account ban decisions are final."

Things that got users banned ranged from "abuse of unintended mechanics" to "use of third party programs".

Any of you affected? If've been very naughty.
