People, people, lets gets civil here, there is no reason that this should go down the "slippery slope" and into the toilet where it is heading.  The way I see it, our thumb nails are a form of advertisement, a way to get others to look at our work.  There are two groups I think who are having the most  trouble with this change.  There are those that have no clue of how to promote there art other than appealing to what they want seen and there audience wants to see.  Perhaps a few lessons in constructive image layout for advertisement would be helpful.  To you it really should not matter and should challenge you to learn that there is more to your art than the aforementioned T&A BTW I don't consider this a true artistic term.  The human body is an amazing work of art but only a handful can appreciate the form fully as artistic. 

The second group having trouble with this are those that are crying censorship, I cannot blame them but lets be fare about this.  Just because it has happened before does not mean it will happen again, sure it means it could. I don't blame them because they are merely reading the past history and predicting the future which we know can eventually happen, it may not be today but it will likely happen one day and it is sad to me as an artist. 
Keep in mind it is not the artist that is under attack here, it is the art itself.  Censorship is a real thing and we are seeing a great change and unfortunately at times a NEEDED change in the way we view such art as nudes.  I fear the days of tasteful nudes and pinups are being dragged into the realm of smut and as such labeled by the PC police and the real PTB not (Renderosity).

I am an artist, as such I hate to see these changes but I understand them and why they are being implemented.  You will hear no protest from me on this matter as I relay don't see a need for it at this time.  But if and when the day comes when MY ART and other good artists in this community is labeled as smut or  "not appropriate"  I will put down my brush and watch as the arts fall back into the dark ages controlled not by the majority but by a few who who believe they alone know what true art really is and how it should be displayed.

BTW Stacey G I have no idea how you can remain so calm but I am pleased you have and that you did not just post this as law and walk away.  We do need open communication if we are to be understood and if we are to better each other and our art, it is the only way IMO.

That's all My opinion take it or leave it.
