After reading the wired article, what's to stop people who work at the ticket printing companies from using their inside knowledge to exploit flaws?
Just like we where prohibited from gambling on the online gambling site i worked for a couple of years ago.
They told me that employees were allowed to purchase tickets. The theory was, if employees can't be trusted to buy tickets, there must be a flaw in the system. And if there's a flaw in the system, then it will be exploited whether you prohibit employees form directly purchasing tickets or not.
That obviously does not map directly to the employees of companies that print scratch-and-win tickets, of course.
