I can not remember the last time I saw a nipple in a banner, so that would not count as porn, even in the US, I think. One can only hope for good taste of the advertisers, because it looks they are the ones that pay for a good part of the existence of Renderosity, due to the volum of V3 textures, models and poses. They serve a market that is, I think, kind of 'playing with dress up dolls' for mostly young boys.
One would expect that kind of images, and the parts to construct them that are ons sale, should be sold on Renderotica, but that seems more to be a fetish place these days. Torturing screaming and bleeding girls is not exactly my kind cup of erotic tea.

I think we can see two different kind of users here at Renderosity and I think the moderators et all should consider giving people the opportunity to choose for the Renderosity Nude OR the Renderosity Non-nude variety. I tend not to look at the banners at all, so I miss the ones that could actually be meant for me. And the advertisers are helped by having an audience that is interested in what they have to offer.

Shonner, anti-gay comments seem a bit off-topic in this discussion (there is a beer belly morph available for most male Poser figures) and here is the plants ads that was on the home page when I opened it to see how big the problem really is (I can recommend that to everybody who thinks that porn has taken over Renderosity, hit 'refresh' a couple of times to see how broad the range of articles is. One tends to remember only the scantily clad ladies (or rock singers for that matter) and glance over the vehicles, houses, plants, elemental effects and cameras).

O, and here is some furniture...

But I am in favour of some kind of split between Poser hobbyists (the 'constructors') and people who are proud that they are making original work (the 'creators'). Because it helps the advertisers and keeps people from NOT visiting Renderosity because they find some of the unasked-for content offending.
