Also, even if AI/ML are not being used to generate fake reviews, they sure as heck are being used to determine the search ranking of products stuffed with fake reviews. Amazon has created a game for less-scrupulous sellers to play, and even they don't know the rules.

I admit that I don't. I am guessing that such things are at present beyond AI/ML. An AI/ML-generated review I would expect to read like... well, like obviously-machine-generated text.

How do you know that? They have a ranking algorithm, sure, but why do you think it's AI/ML (by normal definitions of AI/ML)?
