I was wondering with say these adult sites, What exactly is PPL and what is PPS? What is the difference between the two For example, if you have affiliation with a webcam site, and you send a person and he enters his Name, email, password and " Join for Free" => Is this called a PPS OR Is PPS like , getting another affiliate to write all his details , name, site, address, etc.?? Also which would be the best site in PPL and which one would be best in PPS? Finally what is RevShare and RevShare (Whitehat) , what do they mean exactly? Thank you very much.
