Or: The English version of what I posted yesterday.
Short story: PayPerPost requires you to post a disclosure policy on your blog, to let people know that you accept paid posts. I had to do this.
Long story: Two of my posts were rejected because I didn't have a disclosure policy. For this reason, I had to use PPP's online disclosure policy generator to create a policy for my blog. Basically, it says that I do accept paid posts, but I still keep all my posts honest. So although the available opportunities will affect what I post about, they won't affect what I say about them. Make sense?
Anyway, it's there. You can read all the technical jargon, or you can just read this post. I know what I'd do! :)
