are there fake reviews on amazon
according to which?, nefarious amazon sellers are taking advantage of a legitimate feature called "product merging" that is designed to collate reviews of similar items under a single listing. it is supposed to make it easier for customers to find relevant content, but the research has indicated some vendors are merging old or unavailable products with new product listings to transfer positive reviews between items.
you then see the same item for $5 more and the seller of that item as 100% positive feedback. despite all this data, people often under-price guitars (and other products) on ebay. when we come across a listing that looks like it might have some flipping profit margin in it, we'll analyze the listing detail, pictures, and start communicating with the seller.
