The promoter of an event is perfectly entitled to make up whatever T & C's they care for, as long as it doesn't break the law i.e. "You must take drugs in order to attend.." So if it states no resale or transfer, that's what it means.
Where promoters and ticket agencies do f**k us over is when they then state no refunds or returns. what are we supposed to do.
However, Ebay is a pox for concert goers, particularly if you live in a major city and especially in London.
In the old days, you knew you could go to a gig on the night and pick a ticket or two off the scalpers at an inflated price of course. But the touts' only outlet was at the venue on the night.
However now, due to Ebay, every one can be a tout without having to do the hard work.
Whoever is responsible for ticket sales then compound the issue by putting tickets on sale at stupid times - 9.00am on a Friday is typical. Genuine fans are all at work at that time and can't afford to sit at the computer for an hour trying to book tickets. But the touts can.
And Ebay doesn't even apply it's own rules, let alone anyone else's requests. It's own T & Cs state that transactions must be completed in 30 days - tickets are being offered immediately when they won't delivered for months.
