Well, if you see three guys, who are clearly buddies of each other, getting the maximum of six tickets each, all GA, you know most of them are going to end up on ebay. And I find something morally wrong in having waited all night for tickets, only to have the ticket office run the same gauntlet on the internet as somebody who just woke up. You wanna go to a U2 show? Make the effort and get in line!
At least with waiting all night and getting 6 tickets, to sell half on ebay, at least a fan will make an extra buck. But for the touts the internet is a great tool to score more and more tickets at the expense of fans. I don't want to see corporate business relations getting free tickets to U2 shows when it could have been real U2 fans.
