Quote -  Something you must consider when you create a product and upload it for sale or as a freebie. It is this: Who are the people that will be able to see the promos? If the underaged people are allowed on the site, as they are here at Renderosity, then nudity in any form would not be appropriate. If only adults are allowed on the site, then the packaging and the promos should be up to the creator of the product. If I'm the one that made the product, I will market it as I see fit. Anybody that gets mad because of the way I market my products, is just wasting an emotion on something that he or she has no control over. So I say live with it. Let the vendor market the product in his or her own way.

I think vendors should have a fair bit of control and I tend to prefer it if they have their own style to their promos since it creates a brand.

However, there's a little caveat emptor problem, especially since these are digital goods.  If a vendor isn't showing their product, we shouldn't feel entitled to buy from them.  And it's more than just nudity.  I've seen promos that do a poor job of letting you know what you're getting on numerous kinds of products.  Most vendors do a good job but it's noticeable and annoying when they don't.

As far as age requirements, I thought this site didn't allow restricted promos or gallery images be seen if not logged in.  That's actually Daz's current problem in that their filters aren't set up so they have a strict block for now.  In fact, it can be noted that though they hold themselves up as being family friendly, the old site did allow nudity.
