I've been using fakespot for a few months now and it seems hit or miss a lot of times. I'm hoping that Mozilla has been making changes to improve the implementation of how it checks reviews.

Might be easier to just disable reviews on Amazon if you’re trying to block fake reviews lol.

Amazon's not "in trouble" because they're not fake reviews. They're real reviews left by purchasers, which get bribed to leave them in most cases.

I’m confused. Teachers/professors have said that using AI to detect papers written by AI is highly unreliable. How can this work effectively with a much smaller sample of text to work with (even when it looks for “similarities” between multiple reviews)? What happens in a week when Amazon starts writing fake reviews in different tones/“voices”/styles that are intentionally difficult or impossible to compare?

Its not a technology issue so I dont think amazon will be in trouble at all

So, this sounds like just another AI-authorship detector, which haven't been very successful so far.

With the amount of false posts all over the web I cannot wait.

I guess this is the approach to how AI can be used effectively.

This is nothing to get excited about. Like so many other things there will be constant innovations on both sides. It's an arms race between the scammers and the scam detectors.
