I have heard similar stories of Amazon fraud like you describe. I don't know if everything is true, but this is a problem which can be solved with PKI.
With PKI, the customer reviews a product, and puts the hash of his review somewhere on the internet. The hash might be the hashed version of a JSON like so:
{company: "Stuffed Animal company",
product: "Stuffed Animal",
review: "Very good stuffed animal toy"}
When the buyer tries to buy the product, he will verify each review against a public key, and check if all info in JSON verifies correctly. If it does not, then something fishy is going on.
The only problem is where to put the hash of the review. An official database of some kind is required, by a government or something like blockchain. That's why some people refer to blockchain as a "source of truth". It has the potential to contain information no human power can delete from the internet or modify in any way.

- emporas 3y agoCentralization or decentralization is a mute point. The problem is solved using PKI, which was defined as a theory back in the 90's. PKI can be supported by any government or official with some computers, even private companies can offer support for PKI. There are multiple solutions, but the cheaper solution will be offered by a perfect competition system as economic theory suggests. Anyone is free to choose the most expensive solution if so desires. I don't mind at all if someone pays 1000 times more for the same PKI and uses a more expensive system than a blockchain one.
