I agree that anonymous ranking just invites misuse and we should making ranking identifiable but the problems is that most of these jokers who rank low are not regular members and couldnt care less if we ban them or not. Maybe, if this problem become rampant, we could have period of time before new members are allowed to rank images. Most of the trollers want to cause havoc as quickly as possible and dont have the attention span to hang around. I dont know if this will help or not; its just a thought.
