Images with nudity may get many hits but no more comments than other images. It's the friends/ebots system that controls the amount of comments and votes an image gets. I've seen lots of pretty good, but far from perfect images, that were nonetheless buried under huge heaps of praises. Non regarding any flaws that these images may have. And I saw very good works here, that gathered only few comments. If someone is on many people's favorite artists list, he'll get lots of comments within minutes after uploading an image. Who's not will get only the comments by accidential viewers.
