Amazon announced on Tuesday that it has filed legal action against the administrators of more than 10,000 Facebook groups over fake review schemes.

Amazon claims that its advanced technology and expert investigators confirmed that actors have been leaving fake reviews and that they are being paid by fraudsters.

“Our teams stop millions of suspicious reviews before they’re ever seen by customers, and this lawsuit goes a step further to uncover perpetrators operating on social media,” Dharmesh Mehta, Amazon’s vice president of Selling Partner Services, said in a press release.

“Proactive legal action targeting bad actors is one of many ways we protect customers by holding bad actors accountable," Mehta added.

Amazon relies on honest reviews to help build a trustworthy relationship with customers when it comes to their decision-making process for purchases. Fake reviews disrupt this process.

The lawsuit says that the administrators of these Facebook groups were recruiting the actors to be “willing to post incentivized and misleading reviews” on products that are sold in the United States, the United Kingdom, Germany, France, Italy, Spain and Japan.

One of the groups referenced in the lawsuit is “Amazon Product Review,” which once had 43,000 members but has since been taken down by Meta.

“Amazon strictly prohibits fake reviews and has more than 12,000 employees around the world dedicated to protecting its stores from fraud and abuse, including fake reviews. A dedicated team investigates fake review schemes on social media sites, including Facebook, Instagram, TikTok, and Twitter, and regularly reports the abusive groups to those companies,” Amazon said in its press release.
