Ross Ulbricht, the 29-year-old man accused of operating the digital underground drug marketplace Silk Road, has pleaded not guilty on all charges despite the fact that prosecutors say they have eight to 10 terabytes worth of evidence, reports Forbes. Ulbricht faces more than 20 years in prison on allegations that he engaged in narcotics trafficking conspiracy, computer hacking conspiracy, and money laundering conspiracy related to activities on Silk Road. Prosecutors allege that Ulbricht launched and operated the site under the pseudonym Dread Pirate Roberts. No way is it a description of the actual Ross Ulbricht.
