Is it possible to exploite porn sites for money?

[Cracked1]

Greetings, I recently began to wonder if someone could ever make money through adult websites without ever needing to own a website. It just rattles me that there are tons of porn sites filled with million ads and hundreds of thousands of traffic per day. Surely there must be a way to exploite these websites to promote your affiliate link for example or whatever money making hustle there is. Right?
