'[Thousands of ebooks published each month] are built using something known as Private Label Rights, or PLR content, which is information that can be bought very cheaply online then reformatted into a digital book. These ebooks are listed for sale – often at 99 cents – alongside more traditional books on Amazon’s website, forcing readers to plow through many more titles to find what they want. Aspiring spammers can even buy a DVD box set called Autopilot Kindle Cash that claims to teach people how to publish 10 to 20 new Kindle books a day without writing a word.'"
