Sponsored Review has started to take in adult posts. I am sure there is a niche for it and I am surprised that no one started a get paid to blog for adult websites.
The only problem is that the adult webmasters really like to have their links among the normal blog posts since that convert better.
We got a problem when we had a post about “stretchers” and Paid Per Post rejected some of our blog because of that post.
If you have Google Adsense monetize your blog they can also reject your blog if they find your adult posts offensive.
If you still want to review adult content then you can sign up to Sponsored Review right here
