On Friday, a book jumped to the #1 spot on Amazon, out of nowhere; it quickly became obvious that the author had used a clickfarm to gatecrash the charts. This is not the first time this has happened and Amazon’s continued inaction is increasingly baffling. Last Sunday, a clickfarmed title also hit #1 in the Kindle Store. And Amazon took no action. Over the last six weeks, one particularly brazen author has put four separate titles in the Top 10, and Amazon did nothing whatsoever. There are many such examples.
