1. This goes a long way to show that there isn't probably zero human interaction with the "Amazon's Choice" listings and that it's completely algorithmic.
2. Making fraudulent listings on Amazon is extremely effective. So effective that it can be sent to the top of the charts.
My question is this: even if the listing gets removed, I'm sure it's been up long enough to make an insane amount of money, probably far more than they paid for the review-bots or the stock (if they even sell the correct thing). If they get the listing removed and "banned," what's to stop them from making another shell corp and doing it all again? What's the barrier for entry for fraudulent listings?
Tangentially related, if "Amazon's Choice" is based on reviews and popularity, what stops it from becoming an echo chamber? Age of product doesn't seem like a good factor, nor time spent in the amazon choice spot.
