We're thinking that the Trusted Friends will be enough to removed really terrible content. A person simply has to ask one of those friends to modify/remove something!

The fun part (at least for us when playing with it) is joking around on your friends' yofiles. Because it is anonymous we're always curious who edited what, and you can be a lot more open/honest.
Maybe you could call it an 'assessment', 'evaluation', 'appraisal' or something along those lines, -something that infers that the ownership is not in the subject's hands.
