A site has a responsibility to its members and to those depicted in the images uploaded. The reason I bailed from DA was in my view it ceased to protect the people in the images displayed (i.e. in my view I no longer believed they were willing participants in some images) . With 3D this is not a problem and to some extent we are judged by our peers but with photgraphs it is a different matter. Renderosity's TOS protects us from having to make that decision which I'm grateful for.
