The Farmer's Market was a Tor site similar to Silk Road, but which did not use bitcoins.[78] It has been considered a 'proto-Silk Road' but the use of payment services such as PayPal and Western Union allowed law enforcement to trace payments and it was subsequently shut down by the FBI in 2012.[70][79][80] Other sites already existed when Silk Road was shut down and The Guardian predicted that these would take over the market that Silk Road previously dominated.[81][82] Sites named 'Atlantis', closing in September 2013, and Project Black Flag, closing in October 2013, each stole their users' bitcoins.[13] In October 2013, the site named Black Market Reloaded closed down temporarily after the site's source code was leaked.[13] The market shares of various Silk Road successor sites were described by The Economist in May 2015.[83]
