Just got burned with a 1-star review? Here's what to do.
If you have received a review that is in violation of the terms of that web site, you may contact the site administrators and request the offending review be removed.
Here are Amazon.com’s review guidelines.
Please note that simply negative or critical reviews are not against the guidelines, no matter how “obscene or distasteful” they may feel to you, the author who has worked so hard to write the book.
Q. What if I suspect this is a “revenge review” from someone I know?
A. As long as the review falls within the guidelines, Amazon won’t remove it.
Q. What if this review is obviously a sock puppet, a fake account created by another author to sabotage the competition?
A. On the internet, nobody knows you’re a dog. What is “obviously” a sock puppet to you may not seem as obvious to Amazon.
