Ross William Ulbricht, 29, was arrested Tuesday on allegations he was the kingpin behind Silk Road. A 39-page complaint alleges that he was known as “Dread Pirate Roberts” in forums. The complaint portrays him as a drug lord who made rookie mistakes. The case is a cautionary tale about the asymmetrical challenge in staying anonymous on the Internet, according to the complaint. There is no evidence that the Silk Road kingpin’s lack of opsec was key in drawing the attention of investigators.”]
