Mercari Inadequate protection for sellers

This website falsely claims that sellers are protected while granting return requests for illegitimate reasons. They poorly enforce authenticity claims with fake luxury items abounding. Sellers are wasting valuable time and effort sending items to buyers who can change their minds and return items at a loss to the seller. Buyers are open to fraud. Everyone can be influenced by unwarranted publicly posted reviews. This site is an unmitigated disaster and needs tighter policing or to be shut down.
