Blizzard Entertainment issued a statement, reminding players that the company takes all forms of cheating in SC 2 matches very seriously. They even outline consequences of malfeasance in StarCraft 2 (wow, sounds deadly serious when you put it that way... all this legal mumbo-jumbo gives me goose bumps).

Here's the official word from Blizz:

Cheating in StarCraft II
Blizzard Entertainment has always taken cheating in any form in Blizzard games very seriously, and that's no different for StarCraft II. If a StarCraft II player is found to be cheating or using hacks or modifications in any form, then as outlined in our 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 StarCraft II with his or her account.

Playing StarCraft II legitimately means playing with an unaltered game client. Doing otherwise violates our policies for Battle.net, 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, or exploits. Suspensions and bans of players that have used or start using cheats and hacks will begin in the near future.

You hear that? Cheaters!!
