WHY DO SELLERS OF TRADING CARDS KEEP THIER LISTINGS PRIVATE ?

I HAVE FOUND THAT SOME SELLERS OF TRADING CARDS, MATCH ATTAX AND DR WHO IN PARTICULAR KEEP ALL THIER LISTINGS PRIVATE........ WHY?

I HAVE FOUND THAT THESE ITEMS SOLD ON AUCTION ARE TOTALLY OPEN TO ABUSE BY SELLERS WHO USE A SECOND, THIRD OR EVEN MORE ACCOUNTS LINKED TO THEM TO BID ON THIER OWN ITEMS, OTHERWISE KNOWN AS SHILL BIDDING,

THE PRIVATE LISTING FORMAT MAKES THIS ALMOST IMPOSSIBLE TO DETECT, THEREFORE BEWARE AS YOU COULD BE PAYING A LOT MORE FOR YOUR ITEMS THAN YOU SHOULD BE.

EBAY HAS A SHILL BIDDING PROCEEDURE THAT CAN BE REPORTED IF YOU SUSPECT THAT A BUYER IS SHILL BIDDING, HOWEVER PRIVATE LISTINGS MAKE IT IMPOSSIBLE FOR GENUINE BUYERS TO DETECT IF THEY HAVE BEEN CHEATED, AND EVEN EBAY APPEAR TO NOT CARE IF THIS IS THE CASE AS THEY DO NOT SEEM TO MONITOR SELLERS WHO USE PRIVATE LISTINGS.

MY ADVICE IS TO STEER CLEAR OF THESE SELLERS THAT USE THE AUCTION FORMAT IN THIS NATURE.

GENUINE SELLERS WILL MAKE THIER LISTINGS FULLY TRANSPARENT AND THEREFORE YOU ARE MORE LIKELY NOT TO ATTEMPT TO CHEAT YOU.

I CANNOT UNDERSTAND WHY A SELLER WHO SELLS JUST TRADING CARDS WOULD WANT TO HIDE/KEEP PRIVATE THIER LISTINGS.

HAVE THEY GOT SOMETHING TO HIDE? YOU DECIDE

THIS IS JUST MY OPINION
