I signed up for an Amazon Prime trial a couple of monthly ago, after not using Amazon in a while. Was generally happy with it, but then ordered a kitchen appliance that broke after using it once. Left the most boring and respectful review you can imagine, just stating the facts, how it was used, and that it broke after using it as instructed in the manual. The review was removed within a couple of hours for breaking some non-specific policy, while similar reviews that end on a positive note are shown prominently. I don't want to use Amazon after that. They're clearly just cultivating a review echo chamber optimized for conversion.
