Tickets for Waits' summer shows were limited to two per person but, in an effort to beat ticket touts, a valid I.D. (passport or driving licence) matching the name on the ticket was required to gain entry. Any concert-goer who did not have a valid I.D. or was found to be in possession of a ticket that had been resold – electronic scanners were employed – was not allowed in and did not get a refund.
If you RTFA (I know...), you'll note:
The perpetrators took orders from ticket brokers, who were required to provide credit card numbers and account holder names in advance of a purchase so they could be programmed into the bot.
All they would have to do to defeat the ID requirement is add that to the list of items they need to purchase the tickets. And people would still pay extra to them because 1) they wouldn't have to try very hard to get a ticket, and 2) they would have a much higher chance of getting a ticket.
Real programmers don't comment their code. It was hard to write, it should be hard to understand.
