Despite a crackdown by Amazon, sellers on the platform are continuing to purchase fake reviews for around 15 Euro each (about Rs 1,200), according to a Daily Mail investigation.
The companies selling fake reviews to sellers rely on an army of “testers” who buy the products to post the four and five-star reviews online, said the report on Sunday.
The testers get a refund for the cost of purchasing the products, in addition to a small fee.
The testers buy the products so that the reviews they post get classified as “Amazon Verified Purchases”.
One review firm, AMZTigers of Germany boasts of deploying 3,000 testers in the UK alone.
“We help you get verified reviews from real people. Our more than 60,000 product testers throughout Europe specialize in writing reviews quickly and reliably,” according to the website of the company.
Amazon said it was committed to protecting the integrity of reviews and had spent 300 million pounds in the past year to protect customers from abuse, fraud and other forms of misconduct.
“Our objective is to catch and remove abusive reviews before a customer ever sees it and in the last month, over 99 percent of the reviews read by the customers were authentic,” an Amazon spokesman was quoted as saying.
