I've seen on a few people, some of there reputation isn't fairly earned. It's just a friend giving them reputation because it's there friend. I think it's something that is earned, not just given by a friend for the hell of it.
So that is why I think their should be some sort of rule for the rep, so no one abuses it and reps there friends just to rep them.
