When owning and running an adult website, you are automatically banned from using Google Adsense on them. I have collected a couple of the best sites for you to use on an adult related site. I have tested both of them, and they are not scams. They pay, although not as much as Google Adsense would ever do!
Please let me know, if you have good experiences with other networks, that I should add to this list.
