So what does MARTy do? Scan for exploitative behavior and cut it short. The system monitors player activity for exploitative experience, influence, or reward gains, and people who trip the system stop receiving rewards for a short time. The official FAQ on the system makes it clear, however, that even players aggressively leveling with experience boosters shouldn't hit MARTy's radar. The only way to hit it is by exploiting the game engine for overly accelerated gains, at which point you get shut down. And with City of Heroes Freedom opening the door to everyone, it might be good to have an anti-exploit gatekeeper in place.
