It looks like some governmental authorities have been doing there homework
http://www.bbc.co.uk/news/technology-29950946Silk Road 2.0 and 400 other sites believed to be selling illegal items including drugs and weapons have been shut down. The sites operated on the Tor network - a part of the internet unreachable via traditional search engines.
The joint operation between 16 European countries and the US saw 17 arrests, including Blake Benthall who is said to be behind Silk Road 2.0. Experts believe the shutdown represents a breakthrough for fighting cybercrime.
Six Britons were also arrested, including a 20-year-old man from Liverpool, a 19-year-old man from New Waltham, a 30 year-old-man from Cleethorpes and a man and woman, both aged 58, from Aberdovey, Wales.
All were interviewed and bailed according to the National Crime Agency.
Tor, as well as hosting legitimate sites, is home to thousands of illegal marketplaces, trading in drugs, child abuse images as well as sites for extremist groups.
I think we can expect to see more of these closures, at least until the authorities fall behind in the anonymity arms race that has sped up exponentially since the snowden web monitoring revelations.
