I’m struggling to see how this actually made money. Because presumably the customer is paying for the delivery (as well as the food that was never ordered). So the fraudsters would just be paying themselves in a complicated way. My best guess is one of the following:

1. DoorDash is subsidizing orders so much that this is profitable overall (the amount they pay the driver is more than the customer pays) seems unlikely.
2. DoorDash is paying the driver multiple times but only charging the customer once. But if this was the case how was this obvious accounting issue never noticed? Shouldn’t the books come out even in the end?
