The New York Times reports that hatemongering communities are growing on Orkut. According to the article, these communities are in violation of Google's terms of agreement.

Rather than having Google step in directly and shut these communities down, I wonder what sort of social software solution could be created that would make Orkut self-monitoring and self-policing? These sort of communities devalue the entire Orkut social network. How could this devaluing of the entire Orkut social network be implemented to have a direct impact on the other communities? What sort of solutions could be put into place such that, because of the devaluation, other Orkut communities could and would moderate out of existence the hatemongering ones?
