If you sell stuff there it can be fascinating to what 30 - 100 bids arrive with 1 second to go. But those snipe-bots are being 'driven' by humans who are trying to minimize the price they pay for something.
The statistics work was very nicely done though in the paper.

When reading the article, you have to click "[Who are these robots?]" within the table in the center of the page.
For example, if an item worth $1,000 sells at a final price
of $60, and a bid costing $1 raises the price of the item
by $0.01, the auctioneer receives $6,000 for the 6,000 bids
and $60 as the final price, a total of $6,060. This
represents a profit of $5,060 for the auction site.
Assuming the winning bidder used 150 bids in the process,
they would have paid $150 for the bids and $60 for the
final price, a total of $210 and a savings of $790.
Of course, in a real auction, the winner may well end up paying more than $1,000 for the item...but still, it COULD work. But if bots run by the auctioneer always bid on items, then no actual person ever wins. In fact, the merchandise wouldn't even exist. (Why have a warehouse full of PS3s if nobody but the company ever "wins" an auction for one?) It's like a slot machine that never pays out.And that would be fraud. (Also, an example of shocking greed, considering that the normal penny auction format is effectively a license to print money.)
