None... Most are just cut-n-past of backpage ads anyways...

Or such as with EROS, have shrunk in popularity to complete irreverence, mostly the ads are the same old carpet-bagging girls of a bygone era - having not updated the pics in their ads in 10+ years...  

Backpage is about all we have left that's fresh and current, and while it's a mixed bag, it it the evolution of the best internet streetwalking sight of all time [tcuncovered.com] which I very much miss!
It was the first and best! An electronic extension of Citypages classifieds, it evolved and then went national, giving us the only REAL escort site this nation has left, backpage.com  (A little history lesson on our rich Minneapolis heritage of cash-4-gash)
