Ars Technica: “Fakespot, a useful service that explains how products you’ve never heard of could have 12,000 reviews with a 4.6-star average, has been acquired by Firefox-maker Mozilla, and Mozilla plans to integrate it into Firefox…After you install Fakespot’s extension for Chrome, Firefox, iOS, or Android, it changes the makeup of product pages on Amazon, eBay, Sephora, Shopify, and other e-commerce sites. Fakespot will run through a product’s reviews and then the history of those reviewers, using AI to search for common patterns of paid, astroturf, or other imposter behavior (as Fakespot told Wirecutter’s Lauren Dragan in 2016). The reviews then get a letter grade and a “corrected” average score based on the reviews not cited as fake. Fakespot’s FAQ section doesn’t get much more specific, only noting that it uses “artificial intelligence that has been trained to pick up on patterns” and doesn’t reveal its methods to avoid scammers dodging its tools.”
