Stubhub is the biggest scam ever. I sold two tickets to the Detroit Grand Prix Rooftop viewing. As soon as I received the alert that they sold I immediately transferred the tickets from the DGP site to the buyer. Stubhub claims I never transferred them and then charged me $180. Twice as much as the tickets sold for. I contacted Stubhub customer service and both the rep and the manager were rude and accusatory.
