I wonder how many hashbrowns a "robinhood" style hacker could have sent to strangers, or orders-in-transits discounted to a dollar, before they caught on.
it reminds me of a mysterious building no one knew the origin or purpose of. someone filled a form for poor cleaning then the message bounced around between a dozen cleaning companies who didn't have a contact for it. after decades a cleaning company filled a form because it didn't have a number and wasn't on the drawings.
