I would agree that it's in the best interests of the site to set rules in place to only sell tickets for face value and booking fee. Not only is it bad publicity for the site to be seen catering for ticket touts (not in anyway blaming you neil, blaming the twats who put up tickets for stupid prices) but it's also bad for local people and site users who want to see this gigs but cant. Granted, I haven't actually seen anyone on the site blatantly trying to make money from tickets as badly as the jimmy carr thread, but to try and dispell ticket touting can only be a good thing.
