Back in 1999, Cristophe Bisciglia was a teenage programming prodigy in the sleepy seaside town of Gig Harbor on Washington State's Olympic Peninsula. He was already doing web development work for clients, like Visnet, a tiny ISP in Port Orchard. But a dispute with the owner left a chip on his shoulder. So Bisciglia hacked into the ISP's servers and borked them by sending out thousands of emails, including emails to Visnet's customers pointing out the company's security flaws, according to the Kitsap Sun. While his record was probably cleared once he turned 18, he was convicted of a misdemeanor at the time.
