Wikipedia mainly survives on wealthy benefactors. Amazon donated a million or so recently, for example.

I think the issue is just that having votes publicly accessible can lead to harassment. Sometimes I want to downvote bigots or idiots and not want the possibility of them engaging with me.

Did you use any tools to help build this or did you do it by hand? I remember sethbling put together some kind of world edit tool that did something similar years ago.
