If you don't like the prizes don't play...
If they were to give free hats and customs and stuff, then staff would get even more spam about hosting or whatever.
I agree that staff shouldn't give out dolls or statues, but many players like to worship those in command. As poorface said, staff should definitely not throw down those doll statues so often, because it impedes other players who aren't interested in dolls or don't even own dolls.
I think that staff shouldn't be allowed to give statues or dolls out at all, all it inspires is worship and butt kissing.
