an investigation into a bizarre subset of self-published "celebrity biographies" on Amazon, released under the pen name "Matt Green" through Kindle Direct Publishing, that contained plagiarized and unauthorized material, often with typos and grammatical errors. Tiffany defended Amazon's approach to content control, recalling, "Amazon has already quashed quite a few e-book scams. At first, users could download public domain books from sources like Project Gutenberg, upload them, and sell them to readers who didn’t know better. A policy change in 2011 put an end to that. In 2012, Gawker’s Max Read came across another good one: hundreds of thousands of books that were just compilations of Wikipedia articles with titles like “Celebrities With Big Dicks.” One author he found was just publishing random data sets like “The 2007-2012 Outlook for Tufted Washable Scatter Rugs, Bathmats and Sets That Measure 6-Feet by 9-Feet or Smaller in India.” She argued that while Amazon is known for rampant scams in its self-publishing subsidiaries, the company tries its best to put a stop to the scams when it becomes aware of them, but that outright plagiarism and other illegal content is hard to detect.

Amazon CEOs Jeff Bezos and Andy Jassy have never publicly commented on or apologized to Nora Roberts, Rebecca Maye Holiday or Rachel Ann Nunes for the plagiarism and counterfeit issues, but do feature policies in the Kindle Direct Publishing Terms & Conditions agreement regarding plagiarism and the release of illegal content.
