Amazon has been working for years to clean its sites of fake reviews and fake products. It's still got work to do. From a report: The online retailer on Wednesday filed five separate legal actions through the American Arbitration Association to cut down on a variety of alleged scams used to make money on Amazon's Kindle self-publishing service, according to documents obtained by CNET. "Today's news reflects yet another step in our ongoing efforts to protect readers and authors from individuals who violate our terms of service and manipulate programs readers and authors rely on," an Amazon spokesman said in a statement. He added that only a "small minority" of those using Kindle Direct Publishing engage in such scams. Amazon since 2015 has been using these kinds of legal actions to fight against scams and already sued over 1,000 entities involved in allegedly creating fake product reviews on its sites. The company last year also sued alleged counterfeiters. As part of Wednesday's filings, one alleged scammer used a novel approach to try making money through Amazon. The man named in the filing, Nilmer Rubio, of Olongapo City in the Philippines, allegedly reached out to authors who used the Kindle self-publishing platform and told them he could artificially inflate the number of pages customers read of their books in two Kindle programs. He apparently did this with the use of hundreds of Amazon accounts he created.
