Amazon is worth an enormous amount of money. They can afford to solve this problem. Here's one idea: invite regular amazon users with accounts active for at least > 1 year, who have some kind of verified identity/address, and ask them to become certified reviewers. Give them amazon credits/coupons in exchange for reviews of all the items they've purchased in the last 6-12 months (if they haven't yet left a review for those items). Don't pick people who have only been purchasing a few items from the same vendor. Find people who have a purchase history in line with the average user, not a company insider trying to game the system. This way you don't have this perverse practice of incentivizing people to leave positive reviews on items they want for free. If a reviewer is found to be fake/scamming the system, just remove all their reviews and block them from future reviews. It's time to stop allowing the raw internet to leave reviews. The scammers have won. Time to move on to a more sophisticated filtering system. This feels like email before gmail came along and largely solved spam. It'll get better again.
