Well, another stupid decision made by the blizz is every SC2 key can only have one profile...So basically, we have to show every thing we get from cheating on bnet. I think that's why they consider using trainer in single player game is same as in multiple player game.
They won't ban anyone on SP cheating at all. That would cause a huge outcry which Blizzard's legal team would not want to hear or see.
To whoever said Blizzard responded saying they would, I dunno if your lying dude or having a laugh, but there is no way Blizz would respond like that, let alone quickly to anyone.
Now you are just willfully being ignorant. Life isn't always fair. Their legal team won't have anything to do because it'll never make it to court, their EULA allows them to remove any account for any game experience(that includes sp).
