If it wasn't bad enough having bloggers being sponsored about their materials by PayPerPost but now bloggers have a more serious issue with Google's new implementation. Google will be lowering the PageRank of PayPerPost bloggers which will not only affect the bloggers but PayPerPost as well (less people will see the posts).

IZEA (the new holding company for PayPerPost) CEO Ted Murphy is not surprisingly calling foul on the move, claiming that it’s part of some sort of censorship conspiracy by Google. Better still Murphy claims that it’s part of Google’s attempts to deny competition because PayPerPost is a “a very attractive alternative” to Adsense.
