An anonymous reader writes "Last week authorities shut down Silk Road, an online black market that made use of Tor to hide activity. They also arrested the site's primary operator, Ross Ulbricht, and seized his possessions. Now, an AP report indicates at least 8 more arrests have been made on people suspected to have sold drugs through the site. Four of the arrests happened in the U.K., two were in the U.S. and two were in Sweden. It looks like they're gearing up for more arrests, as well. Keith Bristow of Britain's National Crime Agency said, 'These latest arrests are just the start; there are many more to come.' Authorities are reportedly mining the site's customer review system, which contains months worth of transaction data, for further leads."
