we should alll just watch out for eachother if you see a fishy forsale thread ask the seller some questions even if you dont want to buy anything from him/her. if someone asked this guy to say post good pictures with the date and his name written on a sheet of paper. then people would see his reluctance to prove his good will witch he cant, no one will buy anything.
