Well, they can't do that when there's a secret reserve.
It's no secret what many auction houses do.
For the record, I wasn't implying your site.
I'm just curious what auction site you're talking about. It's not like there are many movie poster auctions around
you have HA, MPE, EMP & my own MPB
are you talking 'actual shill bidding' or are you talking 'bidding against the book' (aka, absentee bids left by bidders to be executed by the auction house as bidding continues)
can you post actual examples of shill bidding the way that one of our members (Zac) has researched ShutterIslandOVMP here on APF?
