The FBI has allegedly taken down (http://www.theverge.com/2013/10/2/4794780/fbi-seizes-underground-drug-market-silk-road-owner-indicted-in-new) the underground drug site Silk Road, where it was allegedly possible to buy drugs such as cocaine, methamphetamine and heroin anonymously through a supposedly secure Tor server via Bitcoin.
According to a criminal complaint filed by the FBI, Silk Road raked in about $1.2 billion between February 2011 and July 2013. The alleged mastermind behind it all, Ross Ulbricht, who went by the pseudonym Dread Pirate Roberts, took home almost $80 million alone. Ulbricht is now facing multiple (http://cdn3.sbnation.com/assets/3326809/UlbrichtCriminalComplaint.pdf) charges (http://cdn3.sbnation.com/assets/3326845/SilkRoadProtectiveOrder.pdf).
Law enforcement agents were able to make 100 purchases of illicit materials on Silk Road since November 2011.
