On a personal note (not speaking as an admin but just a person that enjoys art) I LOVE it when I see a thumbnail that is creatively done without all the T&A cause it makes me so anxious to peek at the full image that I know contains artistic nudity because of the flag. When all that can be done is a thumbnail with T&A in it, I don't care to really go any further because whats the point really? I've seen it.  Artistic nudity I like but I don't care to see a thumbnail that either reveals it all in the thumb or is just a T&A hit button

This is my personal opinion.
