Actually there is, Nike could require a Social Security number to be tied to your NDC account to confirm it's an actual individual and not a randomly generated ATC cart account. This would eliminate most ATC services and people using bots to cart multiple pairs - giving others a more fair chance at copping a single pair for themselves. Considering the lengths people would go to cop a pair of sneakers, I bet most people would give up their SSN without a second thought. A SSN can be easily verified and I doubt ATC services and resellers would resort to using fake SSNs.
