I honestly don't see anything wrong with buying reviews for Amazon if it is setup right. You'd setup a shield where you offer discounted products, and hint for a really good review in exchange for something like a payment. know there is no quick fix solution but you can blockade Amazon for a while until they change their TOS, then you'll update to match it. Honestly though, if you can't be smart and protect yourself from Amazon TOS and you wanna sell reviews, be prepared for the lawsuit incoming.
