We encourage you to treat others the way that you want to be treated. Self-regulation is the success experience of the Internet. Its power also has been demonstrated in the online auction field. Every seller has a buyer's feedback record. New buyers come to the auction, it is recommended to look at the seller's record first, before they put the bids.
Some sellers have pretty long and good records, it increases the confidence of new clients.
And if a seller gets bad comment, he would not show up again. If some problems happened during the trade, you may get the information about the seller from E Bay, and try to solve the problem with him directly. If unfortunately you met a bad guy, who cheated on the trade, then you may put a formal complaint to announce to the whole EBay community. Their data system uploads new reports daily to the database of the Federal Trade Commission and the National Association of Attorney General. Also the reports will be automatically faxed to over 160 law enforcement agencies.
