One year ago i started with an adult blog. But now i learned how to convert adult searchers to quality visitors. CPA gateways has the power to do it. In my opinion people having some mature content should redirect their visitors to a useful quality website (non-adult) without annoying them and give them some free offers through any CPA gateway program. Don't use these gateways directly on adult sites. It may be against program's TOS. Good Luck
