1515 - Offensive Manipulation Defenses

Dr. Beckett addresses a question about “offensive” shill bidding, expanding the discussion to market manipulation as cards are treated like stocks and collectors take “positions” in multiple copies. He explains defensive manipulation as bidding (or reserves/house bids) intended to prevent or thwart recorded sales below a card’s comp range, while offensive manipulation is bidding a comparable copy up above comps to raise the perceived value of cards you already own, which he calls more insidious. Beckett distinguishes legal auction reserves from forbidden self-bidding in online auctions and describes shill/shield schemes involving friends, aliases, or proxy bidders. He also warns that fixed-price listings and brokered private sales can easily be manipulated, and suggests prediction markets could influence perceptions and bidding behavior, emphasizing buyer beware and ethical conduct.
