Ackkkkkkkkkk! This is wrong in so many ways....
First off, DON'T SHILL EBAY AUCTIONS ON BLADEFORUMS! (or anywhere on the net; a lot of moderators will just ban you without warning.) Don't post links to active auctions, don't post the auction number, don't mention there's an auction going on, even if it isn't your auction.
Second, it's a "private auction." Don't you know what that means? Let me quote what our own Bernard Levine is always saying:
Third, something that looks very much like a bidding pool has been proposed. That's not a new idea, gentlebeings; it happens all the time. A group of potential bidders agree not to bid against each other. Instead just one of them bids and then they settle among themselves who gets each item, usually by holding a second auction among themselves. The purpose is to defraud the seller of his fair price (it also defrauds ebay of their fair commission). Usually the participants are more discreet than to make their plans on an open forum in full view of law enforcement.... I don't really suppose anybody here had any criminal intentions, probably you just didn't think about it much, but THIS IS NOT A GOOD IDEA.
Please desist from all these things in future. Do not shill ebay auctions, do not bid on private auctions if you have any sense at all, and do not conspire to form a bidding ring. Don't do it on Bladeforums, and if you have any brains or any ethics, don't do it anywhere else either.
