Blizzard Entertainment has raised the stakes for Cheating in StarCraft II

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.

A permanent ban for an account is apparently a big step. I am not familiar enough with the game to know whether someone could open multiple accounts and use them for testing cheats. This would be a simple countermeasure to an account ban — lessen the value of the account.

It seems to me an even bigger and more exciting step would be if they offered an incentive system for whistleblowers. Then players not only would engage in battle online but also could try to get ahead by reporting suspicious accounts. Or would they have to change the name to StarNarkCraft?
