Representing another win in the fight against paid reviews, a recent report claims that a German court upheld an Amazon case against undisclosed, paid reviews on their site. The provider supposedly offered 3rd party Amazon sellers positive reviews in exchange for some sort of compensation, such as a discount on the product, but the court banned the company from publishing reviews without advertising their "commercial background." The ruling is not yet legally binding as the company can still appeal. Amazon's community guidelines prohibit compensation for reviews, but the practice has still proliferated, prompting Amazon to seek to sue sellers who buy reviews. Amazon tightened up its rules in 2016 to only allow reviewers to accept a free or discounted product as long as they disclose that fact, and use the Amazon "Vine" program to post their opinions.
