The question below refers to a piece of the US satellite turning up for sale on eBay. Many users pointed out in the comments that this would be easy to game - simply take a photo of a bit of rock and post it on ebay. (Settlement details just demand a link to the auction).
So we thought a fair way to settle it would be if the auction was reported in a news site. However, several users who have staked cash on the question aren't happy with this change to the settlement rules.
This is a test case, so whatever is decided here will be used in future for questions referring to an eBay auction.
