Pay Per Post?

The newest addition to ways bloggers can make money comes from a website with the same name.

PayPerPost explains that bloggers can make money by selecting advertising topics from a list - topics include assignments - assigments include detailed instructions for bloggers who will then post in their blog a shiny rendition of what would otherwise appear to be spontaneous advertising.
30 days later a blogger gets paid for their post.

There are clearly a number of problems with this system - not the least of which is: bloggers are generally regarded as trustworthy and valuable for their individuality, their expression of personal opinions - and often readerships will rely on one blogger's ideas or recommendations after the blogger has developed and maintained a reputation.
What happens to credibility in the blogosphere when reputation is marketed?

Naturally, advertising has always selected 'stars' in any field or industry to promote products - but is there an inherent difference in the blogosphere?
Does Pay Per Post (as a now active concept) cross the boundaries or just blur them a little?

The site recommends to bloggers that they pass on the deal if they 'don't own the product' or if the 'Opportunity doesn't feel right' but what's to stop them from saying so one way or the other in order to get paid?
