I remember someone recently reported a scammer selling Linhof gear on E-Bay. Bumping the bid amount up $1,000,000 causes E-Bay to investigate so someone took it upon themselves to bid that much to get the attention of E-Bay.
There's a discussion of this over at lfphoto.info on the Q&A forum. The seller is a scammer, and the bidders are bidding over 1 mil to attract the attention of eBay, which tends to be lax about following up on scam alerts. The pictures are from an auction by Adorama a few months ago, and the purchaser of that camera has been contacted just to be sure that they are not reselling it with Adorama's pictures.
