Just cause it violates a tos doesn't mean they know you are. Its like with pirating... if you know what your doing and have common sense you will never get so much as a warning. Same goes for trainers, if you get coders who know how to kick anti-cheat ass (like caliber) you will never get so much as 1 second ban.
Edit: plus this is micro****e we are talking about.. they are not the smartest when it comes to drm/anti-cheat look at the 360 how easy is it to crack it to play bootlegs?

As long as you're playing OFFLINE, you're fine. If you try these trainers ONLINE, you're an idiot and deserve whatever you get.
