DumbMobs: Creationists gaming Amazon's reviews?

Are creationists gaming Amazon's recommendation system?

I think the creationists have initiated a campaign at Amazon to alter the recommendations. I went to my Amazon page, after noticing a book on Bottomquark, and in my personalized section, where I ordinarily get recommendations about scientific or historical books, because it's noticed these trends in my purchasing, there was this pile of recommendations for creationism books.

The Right Questions by Phillip E. Johnson, Nancy Pearcey How Blind Is the Watchmaker? by Neil Broom, William A. Dembski Science and Evidence for Design in the Universe

Now this didn't just happen by accident. Curious, I went to one of the creationism book's pages. There were lots of comments from readers, most with dozens of 'this review was helpful to me' indications.
