Here's a little suggestion for you. You could change the system a bit, and let the stars represent rating... Then let the members rate each others posts... Or give positive or negative points. But this would work better if you need a certain amount of points/time active, before the points you give count. Otherwise people could make multis.
This could be very confusing too though, but cool too. You just have to trust the population of OWF enough, that they can take this matter in their own hands.
