I don't want to take a look at the site because I'm at work, and value my job, but do you encourage any of the site users to help weed out the crap?
I have a few communities and admittedly, they're not webcam oriented (which likely helps), but they pretty much moderate themselves. (Report links, power-users being assigned moderator powers, etc)
Yes, we did that too, all the obvious ideas we have tried at some point in the last decade.
Having the users police each other works as long as there is no abuse of that power, as soon as they figure out how to game the system you get 'cliques' that will do such funny things as ban all the gays, all the old people, all the women and so on. Pretty soon there'd be nobody left.
I'm 100% convinced that it is possible somehow though, just that I haven't found it yet so please keep those 'obvious' ideas coming, maybe one of these days someone hits the jackpot.
