Here's why I think bidder 13 is a shill.
Look at the times.
You can see several lower bidders were outbid and came back for another try whiich is why the lower numbers are out of order.
Same guy bids it up nearly $5k in just under 90 seconds? Why? To find the reserve? If that was the reason he is stupid as hell to do it 4 days before the end.
You what until 4 minutes before the end.
