It was falling behind. The dodgy stores were getting more creative and Fakespot needed to play catch up. You've got stores that would include a $5-$20 coupon/gift card in the item in exchange for a positive review. Sure, this didn't 1:1 translate but if a user did it would look like a legitimate review. You've got a plethora of LLMs out there just itching to GENERATE. Then an expensive option I was suprised happened…
Some company paid be 100 bucks to change my review to be positive so they sent the money via PayPal no problem then I changed the review to say they paid me to write a glowing review and of course Amazon ended up removing the review for being harmful to their customers
Some Amazon seller included some US postage stamps as a gift, along with a glossy full-color printed offer to pay me cash or more stamps for a positive review.
So I took the stamps to a post office, some kind of manager looked at them, said they'd almost guarantee that the stamps were counterfeit. So I left the stamps and the glossy offer (with the sellers's contact info) with them, to refer higher up to some kind of investigation.
I'd guess probably it will only lead back to some overseas seller who is untraceable, and who just pops back up under 10 new different names. But maybe someday Amazon will be under some kind of KYC-like obligation, to only permit sellers and other supply chain that can be held accountable for illegal/counterfeit/dangerous/stolen/etc. products.
