Blizzard Closes More Battle.net Accounts

Blizzard's official Battle.net website has been updated with news that they've permanently closed 18,000 Warcraft III accounts and have banned thousands more from ladder play. Here are the full details:
A number of additional accounts and CD keys have been tied to the use of a hack or cheat program while playing Warcraft III on Battle.net. In keeping with our aggressive stance against cheating, we have permanently closed 18,000 Warcraft III accounts. 7,600 of the Warcraft III CD keys used with the now-closed accounts have been banned from ladder play for one month, and 1,400 more have been banned from ladder play permanently. Repeat offenders risk having their CD keys disabled, which will result in the permanent removal of their copies of Warcraft III from Battle.net.
