shill bidders?

[ajjohnsonsoxfan]

Just won this 1914 Cracker Jack Joe Wood SGC A from Probstein123. I had read on this board that some suspected of shill bidding so I wanted to test it out. I had the high bid for the most of the auction at $278 and then two suspect bidders appeared in the last minute and systematically bid up the price by $10 increments, so I increased my bid to $500 to see how far they would go. It was like a bot was bidding until the auction ended creeping the price up in small increments until the auction ended at $395. Does anyone recognized these ebay users? i***u ( private ) and t***e .

for t***e his history reads:
30-Day Summary
Total bids: 27
Items bid on: 4
Bid activity (%) with this seller: 59%
Bid retractions: 0
Bid retractions (6 months): 0

for i***u

30-Day Summary
Total bids: 20
Items bid on: 20
Bid activity (%) with this seller: 35%
Bid retractions: 0
Bid retractions (6 months): 1

I think it's strange that someone would have that high of a bidding % with one seller. Either there's a small team of people with multiple ebay account systematically bidding up these auctions or there's "bots" that are programmed to do so. It was only a $120 raise for this particular auction but that adds up to big time $$$ spread out over hundreds or thousands of auctions over time.
