Hi chaser_mall,
I understand your concern and the frustration you would be facing.
However, there are tools that you can use to eliminate such fraud bidders.
Bidder Management Tool gives you the ability to block members who have negative feedback or are not verified via SMS. If you are dealing with high value items, which are specially targetted by fraud users, you will find the SMS facility useful.
You may find more details here:
