What a great news:Blizzard Never Tolerates Cheating
A player appealed
Diablo 3 players in the community to start a movement to reduce the botters in the game. Community manager Lylirra also stated that Blizzard would never tolerate any one who used a bot, a hack, or some other kind of cheat. Exploitative behavior can lead to a permanent ban from Diablo III.

Do you believe that?
I've seen it happen. A buddy of mine had 50 bots gold farming inferno ACT I key spawns. Now he has 49. Never said they were good at it.
