how to promote sites like peerfly ? (strict on traffic source)

Peerfly is a big CPA company but their offers are hard for me to promote.
They don't allow traffic from commenting on others' walls or your own posts with your OWN website link, which contains their offers.
They also don't allow traffic from youtube videos i think?


Please correct me if I'm wrong.

Yes, they are too strict with traffic source. Your site is really good content and traffic you can make money from them.
