There are many 3rd party sites (like fakespot.com) which do a better job than Amazon does and are not incredibly sophisticated. Amazon just doesn't care, that is the only conclusion that is possible to draw from the available data. They are not even doing a half-assed job, we're talking about a fractionally-assed job here, perhaps even milli-asses.

Amazon could easily do at least as good a job as fakespot, and then followup with consequences for review fraud. They could also implement various policies and use the huge amount of data they have available to go well beyond that level and make some headway against the problem. But they haven't done so. Because they can't be bothered. Because people being suckered into buying shitty products hasn't hurt their bottom line yet. They are complicit.

Just because those 3rd party sites are not targeted by fake reviewers.

[InclinedPlane]

They are not 3rd party review sites, they are 3rd party sites for algorithmically analyzing the reviews on amazon for a given product.

How would fakespot be targeted by fake reviewers?

[woadwarrior01]

Adversarial attacks. You tweak your fake reviews until fakespot is convinced your reviews aren’t fake.

Like not post them at once.
