The Word of Mouth Marketing Association has published a very strong article that points out some of the business ethic issues that surrounds PayPerPost.com and their front organisation DisclosurePolicy.org
I stand with a lot of other people in demanding that PayPerPost.com require bloggers to disclose within the article that the post that they are written that the review is a paid review.
Note: The policy for this blog is full disclosure on all reviews that any type of compensation has been provided.
I personally will never link to any site that I determine is a PayPerPost blogger until they change their policies. I just wish that PayPerPost would be a good net citizen. Thanks to Jason for the heads up and of course the damming article over at womma
