So Long, StarCraft II Cheaters! Enjoy the Ban!
Cheaters, be gone!
If you think StarCraft II cheaters are ruining the fun for the more honest players, you'll be pleased to know Blizzard is cracking down on those no good jerks. And by cracking down, we mean they've got license* to ban. In a blog post on battle.net, Blizzard writes that if a player is found to be cheating, they'll be "permanently unable to log into his or her battle.net account."
"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."
*No, really, it's in the EULA.

Protip: SC2 does not require a disc to play.
Maybe they should allow a "cheating server"?
There is no keygen for any Blizzard game that will let you use Battle.net, so stop talking out of your ass kid.
I seriously don't get why people hack. Sure its fun in a singleplayer game were your overpowered and steamroll the AI. But in a multiplayer environment, it's pretty messed up.
Personally I'd like to see their MAC addresses banned as well. So if they want to play/try to hack again they need to purchase a new router/modem.
So I guess playing with a NOCD .exe would also result in a ban, even if you were not cheating.
See.... it's not about fair play, its about piracy!!! Blizzard = RIAA!

Actually, you can change your MAC address by hand. Just to to the MAC Settings of your router and, done.
Too bad they can't send blankets ridden with small pox to that persons home instead...
There's no need for a nocd crack because the game doesn't require the disc to be inserted for playing.
That logic holds true for subscription model games, such as WoW. However, if they ban an SC2 user, they've already made their revenue. Banning won't do anything except maybe encourage the banned user to buy another copy (don't know how likely this is, though)
Err... what? Blizzard has banned thousands of World of Warcraft accounts. Just because they haven't banned everyone doesn't mean they aren't doing anything.
tall tree.
Wish other companies would ban cheaters on certain games I play however.
