DefCon Badge Auction
I am auctioning my DefCon speaker badge on eBay.
The curious phrasing—”upon completion of this auction, Schneier will donate an amount equal to the purchase price to the Electronic Privacy Information Center”—is because eBay has complex rules for charity auctions. So, technically, I am not donating the proceeds of the auction; I am donating a completely different pile of money equal to the proceeds of the auction.
EDITED TO ADD (8/22): Sold for $335. Thank you all.
