I just read Renderosity's TOS -- the term "Adult Content" doesn't appear at all.  There are references made to "Explicit Sexual" and "Pornographic" Content, but there are other kinds of "Adult Content",such as Playboy and other nude images.  Therefore, Renderosity has  "Adult Content".  Here is a webpage that discusses the issue: http://www.eff.org/issues/bloggers/legal/adult.

My concern is: Musicat cannot post a link to some really nice freestuff on Red Viper's site, because that site has some sexually explicit images.  Musicat's intent is not to advertise porn, but rather to help us get some free items.  Isn't it better to let Musicat post the link with an "Explicit Sexual Content" warning, and let us decide if we want to follow the link or not, rather than to religiously follow site policy and deprive us Renderosity Customers of something nice.
