There is a product rating on my unique single quantity handmade item, which has never sold before. Why would eBay even facilitate reviews on non standardized products? How did they even leave a review when they never bought the item? The item couldn't even be in the product catalog.
eBay is allowing buyers to put reviews up for items they never actually assested.
Items that don't need a review because once they are sold that item will no longer be available since it was unique. Items that couldn't honestly have been reviewed.
