Amazon is filled with fake reviews and it’s getting harder to spot them

Since Amazon’s early days, reviews are the one big metric customers have relied on to determine the quality and authenticity of a product. Amazon’s listings often have hundreds or thousands of reviews, instead of the handful found on competing marketplaces. But many of those reviews can’t be trusted. Thousands of fake reviews have flooded AmazonWalmarteBay and others, as sales have skyrocketed.

From Facebook groups where bad actors solicit paid positive reviews to bots and click farms that upvote negative reviews to take out the competition, fake reviews are getting harder to spot. In July, UCLA and USC released a study that found more than 20 fake review related Facebook groups with an average of 16,000 members. In more than 560 postings each day, sellers offered a refund or payment for a positive review, usually around $6.
