I don't see what's so unfair about it when it clearly says on the front page of her website "This site contains no nudity". If someone pays and expects to see nudity, then I guess they can't read.
I can understand what some of the haters are saying, though. She charges people to see her in her underwear while you can see lots of other hot girls naked for free.
I don't mind that she's non-nude. I think she's mega hot and I enjoy seeing the updates, especially the recent ones. But yeah, her being naked would be even better.
