The Diablo III Ban Hammer Cometh

So have you been treating Diablo III as if it were a single-player game and using various bots or hacks in order to make it easier? If so you're in for a surprise, because Diablo III is preparing to bring the ban hammer down and permanently ban you from the game.

From the Diablo III Website:

Blizzard Entertainment has always taken cheating in any form in Blizzard games very seriously, and that's no different for Diablo® III. If a Diablo III player is found to be cheating or using hacks, bots, or modifications in any form, then as outlined in the Diablo III end user license agreement, that player can be permanently banned from the game. This means that the player will be permanently unable to log in to Battle.net® to play Diablo III with his or her account.

Playing Diablo III legitimately means playing with an unaltered game client. Doing otherwise violates our policies for Battle.net and Diablo III, and it goes against the spirit of fair play that all of our games are based on. We strongly recommend that you avoid using any hacks, cheats, bots, or exploits. Suspensions and bans of players that have used or start using cheats and hacks will begin in the near future.
It certainly puts an interesting spin on both always-online, and by extension always on DRM for truly single-player games. Diablo III may be just an outlier due to its multiplayer wrapping, but publishers now have the ability to disable player access to single-player for any cheat they deem as breaking the game. And if the trend continues, we could be saying goodbye to the days when hacks and cheats were modded into single-player titles just to make them more fun.   I really hope publishers never decide to take that step.
