So, years ago I belonged to a gaming forum. Most members, like myself, were pretty much just immature sons of bitches. The forum also had a post rating system. Over time, it evolved into coordinated attacks. So, we'd have this "war" between factions. It became such a headache that the admin decided to permanently turn off the rating system.
This is the second time I've seen it introduced. I'm just a little worried that it might be abused. But I guess only time will tell.
