Gee, yet another ignorant webmaster blaming the program first ... gawd, I'm so happy I don't own an affiliate program to deal with these people
Selling cams.com is
not the same as Peekshows or most other live chat sites. Some of their private chats are more expensive than the competition, so you might want to account for that ... saying "FREE LIVE SEX HERE!!!!" probably won't convert on them that well (!)
Neither will spammy iframe pages ... you have to use a little more to pre-sell the customer. And consider the sliding scale revshare now + higher per-minute rates and you can make good coin with some long-term tunas / big fish / whales.
I don't do as well as I'd like with them, but instead of blaming the sponsor, I look in the mirror. Maybe you should try that too?
