How a player with a “useless” item almost took down EVE Online’s entire economy
When I played Everquest I did a very similar thing, except without the ship component. We found an obscure item that was not in any of the well-known databases, which is fairly difficult considering how far reaching they were.<p>Then we advertised a 'want to sell' considerably lower than the 'want to buy' we advertised in a different zone, both very high prices.  Someone decided to make a quick arbitrage sell and found out I didn't want that item at all.<p>I'm sure some have learned the risks of arbitrage the hard way through these games, among other things.
