Youtube vids do more cam sales than adult sites: pay users, not free signups.
I was checking the http referrer of pay users converted from traffic sent by affiliates, and best conversion ratio is from youtube vids definitely, for example this one:
https://youtube.com/watch?v=7h-qV3M_0pg
The guy do not even own a domain name or site, he post in youtube a video of a clothed girl who dance and in comment post a redirector "is.gd" to his affiliate link.
People sending hits from adult sites have very low conversion ratio and must pay an hosting and domain name bill, now I wonder...
