Yeah they don't care and are overly confident really most of the says are now business and listings are flooded with Chinese listings many of which are duplicated, most don't pay tax either as they "only store stock in the U.K." and a lot of low cost junk where very little is made sub £10 stuff so they need to make more on the bigger value stuff! No investing in stopping the scams or shill bidding! It's just another reason for the likes of Vinted, sphock, gumtree and Etsy to grab a bigger share from the private sellers and the business seller will move to Amazon marketplace for new products at least. The only way to stop blatant profiteering is to stop using them but until people do they will get away with it
