I now know who is behind it and why.
This is what I've learned. An indie author has a beef with a book blogger who happens to support my books. This indie author went to her street team and organized readers to attack my books when they release to "pay back" the blogger for not liking her book. She also went to her indie author friends and had them join the bandwagon. These attacks have been on my last 3 releases.
Take a second to let that sink in.
My books are being attacked because an indie author doesn't like a book blogger…who happens to enjoy reading and supporting my books.
It's good to have answers. Thank you to the bloggers, reviewers, readers, and especially to Amazon for coming forward and supporting my books.
I know readers will wonder how reviews can be removed and it's quite simple from what Amazon is telling me. If 9 individuals click on the "report abuse" button on the review, an auto-bot removes the review automatically from the book page. Bam! They're gone. When the professional reviewer tries to post the review again, they're blocked with a message informing them that their review sounds like a similar review and the reviewer is biased toward the author (read the reviewer is trying to put up multiple reviews for one book and that's cheating, even though the Amazon auto-bot hid the first review), and that blogger is blocked from reviewing any more of my books again.
