Why is it failscouts domain to solve? That should squarely be laid at the feet AMZN, not some 3rd party. Seems like such a strange twist of logic to be a question like this.
It's why reviews, in particular AMZN's, are just not worth the trouble. Too many fake ones, so people have come up with "clever" rules for themselves to only read the negative ones. Somehow, they believe the good ones are gamed, yet the negative ones are not? Another strange twist in logic. Once you believe the system is gameable, then the whole system is suspect.
