Many of EVE Online's most prolific marketeers use courier contracts to collect together items from their region-wide buy orders but that's not all they can be used for. Courier contracts were originally intended as a way to pay another player to haul items for you securely using a standard collateral deal but if you know how, they can also be used for theft. Over the years, players have found ways to use courier contracts for profiteering, gambling, and even corporate theft. In EVE's Machiavellian universe, anything you can get away with is fair game. This includes twisting an innocuous game mechanic like courier contracts into a tool for theft and piracy.
