A law enforcement consortium, comprised of the United States Federal Bureau of Investigation, the United States Immigration and Customs Enforcement division of the Department of Homeland Security, European law enforcement agencies consisting of Eurojust (the European Union's Judicial Cooperation Unit) and Europol (the European Union's law enforcement agency) have mounted a successful seizure campaign (monikered Operation Onymous) targeting over 400 suspected nefarious dark market sites resident on the TOR network.
Key quote from the TorProject: 'In a way, it's even surprising that hidden services have survived so far. The attention they have received is minimal compared to their social value and compared to the size and determination of their adversaries.' - via a post by TOR Executive Director Andrew Lewman
