Using the crawler we explored a connected component of more than 34'000 hidden services, of which we found 10'000 to be online. Contrary to folklore belief, the visible darknet is surprisingly well-connected through hub websites such as wikis and forums. We performed a comprehensive categorization of the content using supervised machine learning. We observer that about half of the web content is related to apparently licit activities based on our classifier. A significant amount of content pertains to software repositories, blogs and activism-related websites. Among unlawful hidden services, most pertain to fraudulent websites, services selling counterfeit goods, and drug markets.
