Is it possible for an online seller, say for a site like Etsy, to post his/her own reviews, thus giving the impression that they have tons of 5-star reviews? (or hack the system in order to do so?) On Amazon, this isn't the case; they label each review as a ''verified purchase.'' My friend is dealing with a horrible seller on Etsy, who still hasn't shipped her package, but is assuring her that he has (she checked with the USPS and used the tracking number Etsy provided). His reviews paint an entirely different picture of this seller, and I can't help but wonder if there's a way to fake reviews. Just wondering.
