Accessing certain features, such as e-mail, private chat rooms, webcams, blogging, and a webzine, requires paid membership.
Adult Friend Finder has an affiliate program, whereby webmasters are compensated for referring users to the site.
Which sounds very cheap until you consider that some of the women there are after points which can be changed to cash and not looking for dates.
So it appears to have an element of being a cam site while also being a social and dating site.
As a result, Conru started Adult Friend Finder, which he described as "a release valve".
