If you mean the touts hanging about outside the concert, and those around the theaters, etc., I never do it. Not just for 'moral' reasons, but also afraid of getting ripped off and ending up with a counterfeit ticket. Will probably do seatwave, though, as I have checked out their website and it looks pretty on the up and up. I guess it's just another form of scalping, as the tickets are really marked up, but at least I will know they're genuine.
