Blizzard appears to have begun banning scripters and botters at a greater rate than ever before. It's not that the developer hasn't already been banning reported instances of cheaters, but they've only just begun to expand the focus of their efforts on players who use automated scripts for the auction house and for farming.
At the present, script programs allow the automation of farming certain boss monsters in the game. According to posters on the official Battle.net forums, the most common use of these scripts is to farm Sarkoth in Act 1. Blizzard has attempted to limit these instances not by nerfing the monster's drops, but by enabling the game limit to prevent players from creating too many new games.
Needless to say, the developer isn't too keen on sharing its detection mechanisms for fears that cheaters will circumvent these measures. If you've used these programs before, now might be a good time to stop.
Here's the message you'll receive in your e-mail should your account be banned for cheating:
