actually this goes to all sites and blogs that use sponsor content. And now that Google is using more human reviewers it will be even more difficult to skirt around the algorithm. If you're on page 1 your site is being looked at by at least 6 humans or will be soon

I went trough the reviewer test, other than it being very difficult, it becomes subjective past the top two site ratings which are kind of obvious what sites they should be applied to. Past those, and reviewers have quite a bit of leeway on how they rate a site.

They have 6 people looking at the same site, and if the ratings from all 6 differ they have to come to an agreement before the final site rating is assigned but I would imagine when it comes to porn they aren't going dwell over it that much.

Basically the rules are the brand + it's extension content (video/galleries in the case of sponsors), + social presence. Followed by authority sites. And then everyone else
