Of course they morally shouldn't, but its like Quincy said, if there is a demand for it, like at a sold out event - and there is demand for it when you legitamitly can't go then it is acceptable because that's the economy we live in. If I was in this situation, I would offer it at the face value of the ticket and if someone was to offer me more then It would be sillly to turn it down - plus that's how an auction works if people are willing to pay that, that's there problem. A tout forces you to pay £40 over the price. A legitimate e-bay sale you are asking to buy it at that price. So, yes, in some cases that is morally wrong, but we shouldn't clamp down 100% on all ticket selling by unofficial methods as it would compramise the economy we live in. Plus, like I said before, impossible to police.
