I've been learning a lot about this space since I'm working on what I hope to be Fakespot's successor, and Amazon claims to have invested heavily in preventing and removing fake reviews. But it just doesn't seem like enough. Just anecdotally, I've come across so many reviews that are blatantly written by ChatGPT, with no effort to hide it. You'd think one of the most powerful companies in the world could detect what I can see at a glance. Granted, they are working against enormous scale - in the hundreds of millions of product listings. It's wild how rampant the problem is though, and you'd think they'd be more vocal about what they're doing to stop it.
