Blizzard just stated in their forums that they had banned ’320,000′ accounts over the years for WarCraft III and Diablo II.

We’ve recently banned over 320,000 Warcraft III and Diablo II accounts that were found to be violating the Battle.net Terms of Use. 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.

We would like all players to remember that abuse of unintended mechanics and/or use of third party programs is a violation of the agreement made when signing on to Battle.net, and can subject your account to disciplinary action up to and including a permanent ban of its access to the service. These types of activities can severely impact the stability of our servers, and we’ll continue to aggressively monitor Battle.net in order to protect the service and its players from the harmful effects of cheating.

Many account closures come as the direct result of tips emailed to our hacks team by legitimate Battle.net users.

Ha good for them, since most of them were probably using maphacks and run bots. However, 300,000 accounts does seem kind of little to me, I guess I was hoping to see millions for Diablo II.
