We, along with many other reviews sites, bloggers, and individual reviewers, have been banned from posting reviews on Amazon.com because, according to them, we've violated their guidelines. For example, Midwest Book Review, one of the largest and most known review services has been banned. They are known to give free reviews and are highly regarded in the industry. Yet, Amazon.com continues to keep many reviewers that have blatantly violated the guidelines.
Some of us that have been banned have book review sites and offer other services besides free reviews or those included in the publicity package. Amazon.com claims this is in violation of their guidelines, however; they themselves are violating their own guidelines by offering outrageously priced book reviews. As owners of CreateSpace they offer paid reviews. As well, there are many other review sites that charge enormous fees.
We feel Amazon.com have banned us because we are in direct competition with them and our fees are tremendously lower than theirs.
That said, authors/publishers are able to post excerpts of the review we provide under Editorial Reviews through the Author Central account on Amazon.com. Many authors have done this as they feel the excerpt has more credibility in the Editorial Section than it would have in the review section. Instructions to post excerpt under Editorial Reviews.
