Here's an idea that would never work: how about a financial incentive straight from Amazon for leaving negative reviews? Let's imagine a universe where Amazon does away with the star rating system and replaces it with a pro/con "tag" list. (e.g. "high quality" "smells bad" "broke quickly"). They then only allow reviews from verified buyers of an item. Amazon then contacts some percentage of said buyers proportionate to the number of reviews the item has has/how recently it was listed (to establish a baseline) and offers a small account credit for a reviewer to clearly state at least one thing they didn't like about the item, requiring a response other than "nothing". This would identify trends or common failure points. The more negative reviews a product has, the higher the reward that Amazon hands out. Scammy sellers would have to consistently "beat Amazon's offer" to get fake positive reviews. In this hypothetical universe... would sellers setup shell accounts to purchase their own inventory and tank their other products' reviews for Amazon credit? Or would they buy out their own inventory to increase the ratio of positive to negative reviews? Would the cut that Amazon takes for using their platform outweigh the cost of paying off buyers/purchasing their own inventory? Would the cost to Amazon be worth the increased customer engagement?
