"Yet while anonymity offers a potential bulwark against surveillance, for those who do not wish to be watched, it has also helped in the development of that part of the online world known as the dark web.
Sites on the dark web like Silk Road have used Tor technology to hide their location and yet still be available to users who wish to visit them.
The dark web has now become a focus for law enforcement officers who believe it is facilitating a variety of illegal activities including financial crime and child abuse."

"Wikileaks, with its simple 'keep the bastards honest' ethos, aims to discourage unethical behaviour by airing governments' and corporations' dirty laundry in public, putting their secrets out there in the public realm. The site won Index on Censorship's 2008 freedom of expression award because it's an invaluable resource for anonymous whistleblowers and investigative journalists.
Among Wikileaks' recent triumphs are its publication of top–secret internet censorship lists. The blacklists from Australia, Thailand, Denmark and Norway demonstrate exactly how censorship systems are abused to suppress free expression. The Thai list featured sites criticising the country's royal family and the Australian blacklist turned out to include a school canteen consultancy. Despite its child porn mandate, less than half of the Australian blacklist were linked to paedophilia. Also on the list were satanic and fetish sites, anti–abortion websites, and sites belonging to a kennel operator and a dentist. Publication highlighted the lack of transparency in the process and gave impetus to the 'No Clean Feed' campaign which opposes the Australian government's internet filter proposals."
