Fiverr.com is a website where people will do all sorts of things for as little as $5. People will draw illustrations, fix problems with website code, promote things on their blog, or compose a podcast jingles. Some people offer to write a 5-star review for any book or product on Amazon for $5. It is against Amazon's rules to write shill reviews, and now more than 1000 alleged shill reviewers are getting sued. Amazon has sued websites that offer shill reviews in the past, but this is the first time the company has gone after individuals.
From CNN:
Court documents say Amazon conducted an "extensive investigation" into the Fiverr users. It claims some tried to dodge Amazon.com's review controls by posting from different accounts and IP addresses.
"In at least one instance, the seller of a 'Verified Review' was willing to receive an empty envelop, not the product itself, simply to create a shipping record," the court filing says.
