The scam involved vendors sending customers a list of products to leave five-star reviews on. The customers would buy the products, leave inauthentic five-star reviews, and then receive a PayPal refund while still getting to keep the product. There are plenty of ways to gauge which reviews are genuine and which are not. According to Safety Detectives, you should be wary of products that have a lot of positive reviews that use less emotional language or include irrelevant information. “If a product’s five-star reviews have been posted before the product was listed, or over a short time-span, they could well be fake,” the experts at Safety Detectives add. “Several of the five-star reviews may highlight the same plus points, or the reviews could generally lack variance—not revealing anything about each individual’s specific experience. Fake reviews might contain lots of generic keywords, too, or reference the brand’s name multiple times.” RELATED: For more up-to-date information, sign up for our daily newsletter.
