It would be really nice to have a browser extension that shows the amount of other reviews every reviewer has in the last n months. Someone with 20+ review can not really be trusted and can be filtered out.
Or even better: If Amazon would spend some of their AI departments time and delete those fake reviews on a daily basis. So tired of them.
The article actually mentions Fakespot [1] which has a chrome extension as well as ReviewMeta [2] which as far as I can tell doesn't. Neither do exactly what you're asking but they seem quite useful from a quick investigation and highlight some of the issues highlighted in the article when you look at the linked product.
Might be worth checking out ReviewMeta - it scans Amazon product reviews for unnatural review patterns and provides a report highlighting suspicious activity. They also offer a browser extension.
