Deadmau5's email has multiple connections to every single email Vangaboo has ever registered with, and Shiebel has additionally strong connections.
They type exactly the same, and Deadmau5 went off for 5 minutes mysteriously the minute Shiebel joined the thread. Which is funny because there's no way he'd know to come here other then being Deadmau5. So yeah, Vangaboo sucks at making alts.
