i see this issue on 1p buyers who are only buying it as they want feedback i reported them and nothing ever happens (i ended up getting my ebay seller account blocked from selling as i was refusing to give feedback so they would leave negative or file a dispute) there address are fake and some poor person was likely getting 100 sim cards a day in crap mail
i really should take ebay to court or somthing as they blocked my account because i was not complying with scammers demands
