This isn't to debate the good vs evil of porn, but to state my opinion why the topic of accurate gens is somewhat "taboo"

Renderosity is a family-friendly site. Always has been. The Poser product is a family-friendly software application. Always has been. Poser is also sold to the educational market, where minors use it. That's why gens are "off" by default, and the default textures are "non-gen-ified."  Characters that do have gens are given that as an option, not as a default. And in most cases, the gens are probably not as detailed as those who create adult-oriented content would like.

I have no problem with people who create adult-oriented content. Full disclosure, I don't do nudes that often, but if I do they are more "artistic" than "here it is".  However, if I was a parent with under-age children that want to learn how to use Poser, I don't think I'd be comfortable with the prospect of them seeing explicit renders and discussions about things that are probably better covered at 'otica, where there is an age limit on joining. 

I'm not trying to create a rant, just explaining a side of the issue that is often not considered.
