I also found that a lot of the same content is sold not just here at Renderosity, but also on Renderotica, with genital bits and the whole thing.. That alone should put this one to rest. :)

Clauses like the one mentioned earlier is most likely a blanket legal protection, for the site and creators, against real problems. (Found the exact same phrase on hundreds of sites when googling it.)  I have a tendency to get a bit paranoid sometimes..

I don't think I have to stop making poser art, and thanks for the help.. :)
