It is for complete perverts. I couldn't believe how many people are shameless. But the amount of free features are impressive and for all the nudity, they could charge admission to see it.
If you are looking for something soulless and dirty, I am more than likely going to refer you to Fling.com.
Good for what it is...

This site fakes user ids and photographs. For example, the opening page is headed Search Results, and list a picture of a "Beth - United Kingdon". Actually the only userid in the uk called Beth is a male (probably not a bad chap but hey, I'm looking for girls) and I consider that my money is now fraudulently taken.
