The Amazon reviews thing I assume is referring to Fakespot, which Mozilla bought some time ago.

But I’m confused about their “AI’ed it up” comment because from the very beginning Fakespot was using ML to determine the tone of reviews and whether or not they were lying about the product/paid reviews by the seller.

You really haven’t thought this through. What happens if I email you a bunch of illegal pictures? Guess we’re both going to jail.
