We contacted Blizzard ourselves for a bit of clarification on the matter and were given a statement, which you can read past the break.
"Blizzard Entertainment is not banning StarCraft 2 players just for using single-player cheats. There's been some confusion in the last couple of days about the suspensions and bans meted out to players caught cheating in StarCraft 2. It's important to point out first, that many of the 3rd-party hacks and cheats developed for StarCraft 2 contain both single- and multiplayer functionality. In order to protect the integrity of multiplayer competition, we are actively detecting cheat programs used in multiplayer modes whether there are human opponents or not.
That said, players who opt to use any type of 3rd party hacks do so at their own risk -- there are already built-in cheat codes for StarCraft 2 single-player that can be used safely. Blizzard Entertainment has always taken cheating seriously and will continue to aggressively crackdown on players who cheat in our games."
