Seeing bot accounts get banned never gets old and this week Blizzard made a sweeping smash of those annoying little bastards in Diablo III. In a recent post to the Diablo III forums, Community Manager Lylirra delivered the good news about the purge and about some new handy features that will be on the way in the future to help report them a little quicker.
We've recently issued account bans to several thousand Diablo III players who were found to be using botting programs while playing. In addition to undermining the spirit of fair play, botting, hacking, and other forms of cheating can also cause technical problems with the game as well as contribute to performance issues with the Battle.net service. To learn more about our exploitation policy for Diablo III and how it may affect your gameplay, please visit our official support site.
As always, maintaining a stable, safe, and enjoyable online environment for legitimate players is very important to us, and we'll be continuing to keep watch on Battle.net and take action as needed. In the meantime, if you wish to report the possible use of botting programs to Blizzard, please see this thread for more information. (We will also be adding the ability for players to report this kind of behavior directly through the game client in a future patch.)
As someone who played Diablo II an almost unhealthy amount, I can attest to some of the issues these little cretens could cause. They shall not be missed.
