May be the spotting is actually not that great. One way to test it is to find a popular, known-to-be good product that you have and see what the result is. The example I tried was the Instant Pot (which is rated D):

Right. And the point of my test is to test fake spotting algorithm by finding product that is highly unlikely to have fake reviews.
Just did a quick check again, the Canadian instant pot reviews are now rated as F while the US ones are rated as A. Same product, both ship and sold by Amazon, the algorithm returns polar opposite result.
I don't understand. If your product is already rated 4.5+ stars with thousands of reviews, what's the point of adding fake review? How does that boost sales?
Why waste engineers times when you're on top with hardly any competition? Google and Facebook only started caring about fake information under congressional pressure.
Fake reviews are usually positive. That is just advertising for Amazon which unlike normal advertising HIDES the fact that it is paid-for advertising. Amazon benefits when there is fake positive advertising about stuff sold through them.
Now it is possible that Amazon actually does a good job of stopping fake negative advertisement on its site. Good for them. What would stop them? I don't think there are any laws against putting more money into stopping fraud which does not benefit you than fraud which does.
Jeff Bezos is no idiot....he knows he can let this run until it starts to become truly scandalous, and then Amazon can have a big showy come to Jesus change of heart, and all will be forgotten. Rinse, repeat.
When a customer is burned by a bad product with excellent reviews, especially more than once, ordering from Amazon could quickly become more trouble than it's worth.
I think in that case people will fall back to buying the brands they know rather than trusting the reviews. There are plenty of other reasons people are loyal to Amazon, so bad reviews on their own, I don't think, will be enough to stop people shopping there.
Money. They only care about short term sales. Amazon doesn't care about how much you trust amazon... for now. Once they've lost everyone's trust then they're start to care.
As far as I know (and in my experience so far, e.g. reflected in very lenient return policy) customer trust has been their highest priority from their beginnings, which is one of the main things that made them successful in the early web in the end.
They have been risking it by their issues with counterfeit products and fake reviews only in the most recent years, but I would be surprised if they had no engineers who are thinking about ways to solve these problems.
