Blizzard's Battle.net site is reporting that they've closed down no less than 112.000 accounts because of cheating and that they've listed the CD keys so that if some of those people would cheat again, Blizzard can easily block the cd keys and permanently get rid of those cheatersNumerous additional accounts were tied to the use of a hack or cheat program while playing Diablo II on Battle.net. In keeping with our aggressive stance against cheating, we have permanently closed over 112,000 of these accounts and documented the CD keys with which they were used. Please note that repeat offenders risk having their CD keys disabled, which would result in permanent removal from Battle.net for their copies of Diablo II.
We have also identified those accounts with which a "map-hack" program is being used. Map-hack programs give players who use them unfair advantages over other players. As with any third-party program, using them to affect play over Battle.net violates our End User License Agreement. Accounts that continue to be used with a map-hack program are subject to closure, and the CD keys with which those accounts are being used could be disabled.
