Griefers Are Mini Terrorists
I play Rockstars Live on my iPod Touch and there are lots of griefers that I run into from time to time. They're easy to spot. These are the people that will add you to the challenge list (or CL is a list where everyone can see and battle you) for no reason and/or make demands on your comment wall like asking you to CL them or saying something offensive. If you ignore them and don't respond they quickly move on and I mean quickly.
