There's a simple way of stopping touting dead in it's tracks. I have even spoken to Harvey Goldsmith's office with these idea's after getting pissed off with this happening.
1 - Tickets must be purchased at the venue using a credit card only. What happens is touts pay schoolkids or local scally's to stand in line all night, and they all buy the maximum allocation allowed with cash. If it was credit cards only, you wouldn't have bus loads of kids standing in line. This happens with all major gigs, I have even seen these scumbags handing out packed lunches before.
2 - When the card is purchased, the card holders name must be printed on all tickets.
3 - When entering the gig, you must have proof of I.D. - this must match the name of the person who is on the ticket. Obviously If there is a group of you, the original named buyer on the ticket must be present. If, for example a mother buys her daughter and friend a ticket, the ticket agency must put the daughters name on the ticket.
4 - The best seats available, when sold, can only be picked up with the card holder present on the day of the gig. This way people wouldn't be able to buy tickets with the sole intention of selling them. If you have a front row seat, you will not be bothered about having to pick it up on the day.
There are holes in these ideas, but there are ways to make touting very difficult, if the will is there....
