On Saturday, a Reddit user posted a message from the site's administrators, which has since been removed. The message claimed vendor EBOOK101 hacked the site and stole 5400 Bitcoin.

"Sheep is down. We are sorry to say, but we were robbed on Saturday 11/21/2013 by vendor EBOOK101," the message reportedly said. "This vendor found [a] bug in [our] system and stole 5400 BTC - your money, our provisions, all was stolen. We were trying to resolve this problem, but we were not successful. We are sorry for your problems and inconvenience, all of current BTC will be ditributed to users, who have filled correct BTC emergency adress [sic]. I would like to thank to all SheepMarketplace moderators by this, who were helping with this problem. I am very sorry for this situation. Thank you all."

Details of the incident are still unclear. Angry former users of the drug bazaar are pointing fingers in all directions, mainly on Reddit, and mounting a cyber-manhunt operation to track down the robbers. Many believe the heist was a scam, and the No. 1 suspect among Redditors is the Sheep Marketplace administrator, a Czech citizen named Tomáš Jiřikovský. Rumors of suspicious behavior from Sheep Marketplace's administrators began in late November, as documented on the website SheepMarketScam.com.

"You run a site partially dedicated to thieves and scammers selling their wares, yet somehow wonder how it ends up getting robbed?" wrote Reddit user twigburst.

Jiřikovský has, in turn, denied the accusation in a Facebook post.
