Blizzard reports that a Denial of Service attack is currently being perpetuated on Battle.net, the favorite multiplayer game hosting service for Diablo, Diablo 2 and Warcraft 3, that is causing the server to crash by some people who aren't terribly interested in winning any awards for being nice.

Blizzard states that users involved in this malicious act will be banned, and their associated characters and accounts promptly deleted.
