I'd love to see his original letter. What prompted him to whinge about them in the first place?

edit: by the way.. I'm hardly surprised at the (lack of) action from our regulator.  I once reported to one of our consumer affairs agencies about an Australian guy who was pimping some quackery to cure aids - and was told that 'youtube' was out of their jurisdiction :/  It was bizarre - like if he'd put the ad in a local paper they'd be all over him, but just because youtube is out there on them foreign internets - free pass.
