The FINANCIAL -- Amazon’s top reviewers in the UK appear to have engaged in fraud, leaving thousands of five-star ratings in exchange for money or free products. The company took down 20,000 product reviews following an investigation by the Financial Times.
Justin Fryer, the number one Amazon reviewer in the UK, left a five-star rating once every four hours on average in August, according to the FT’s analysis. Many of these reviews were for products from random Chinese companies. Fryer then seems to have resold the products on eBay.
A FIVE-STAR RATING ONCE EVERY FOUR HOURS ON AVERAGE
According to `the VERGE reports, scams like these typically start on social networks and messaging apps such as Telegram, where companies can meet potential reviewers. Once the connection is made, the reviewer chooses a free product, then waits a few days to write a five-star review. After the review is posted, they get a full refund, and, at times, an extra payment.
Amazon has a specific rule against posting reviews in exchange for “compensation of any kind (including free or discounted products) or on behalf of anyone else.” But nine of the 10 top reviewers in the UK seem to have broken that guideline, engaging in suspicious activity. The 20,000 reviews that were removed were written by seven of the top 10 reviewers.
The company was alerted to Fryer’s activity in early August. At least one Amazon user reported the man’s questionable ratings to CEO Jeff Bezos. This user was told the company would investigate, although it failed to take action until today.
Fryer maintains that he definitely did not get paid to post fake five-star ratings, and he says that his eBay listings for “unused” and “unopened” products were extras, according to the Times.
