Came across some interesting things today when looking into a project for someone. Not so much surprised these exist; but very interesting in seeing the amount of traffic they get. Plenty of topics have started here where providers ask and talk about alternative methods to sell themselves sans physical contact with the person paying, maybe these can help shed some light (or at least discussion).

and more.
Seems the premise here is that you can use these places to sell your services (sell panties, sexting, chatting, pics, videos, etc.). Going so far as to even have 'verified' and 'trusted' sellers/buyers.
