Shortly after restating their stance on cheating, Blizzard announces several thousand Diablo III players have been banned "for cheating and/or using botting or hacking programs" (thanks Ars Technica). Here's word:

We recently issued a round of account suspensions and bans to several thousand Diablo® III players who were in violation of the Battle.net® Terms of Use for cheating and/or using botting or hacking programs while playing. In addition to undermining the spirit of fair play that’s essential to everyone’s enjoyment of the game, botting, hacking, and other such exploitive behavior can contribute to stability and performance issues with the Battle.net service. As always, maintaining a stable, safe, and fun online-gaming experience for legitimate players is a top priority for us, and we'll be continuing to keep watch on Battle.net and take action as needed.
