Silk Road Anonymous Marketplace is undergoing upgrades to the system in the wake of Sheep Marketplace and Black Market Reloaded going down. The reason for the upgrades is to cope with the increased traffic received since BMR and Sheep have gone down.
Sheep Marketplace went down a couple of days ago after it claimed that a security leak contributed to someone hacking them and stealing all of the bitcoins which are rumored to be around the $40 million mark. Many are thinking that the whole site was just a scam as many vendors apparently were offering massive discounts just before closing prompting many people to believe it all was just an elaborate hoax to get more bitcoins deposited int he system before they all took the money and ran.
Black Market Reloaded is now reportedly closing as well because the administrator says that because Sheep Marketplace is closing then it will not be able to guarantee the anonymity of its users with the new influx of users that will come over from Sheep marketplace.
It seems as though Silk Road 2.0 has risen to the top of the tables to be the biggest black market website in only around 1 month. This also enforces the fact that you want to take your online anonymity dead serious and take every possible precaution you can to be untraceable and encrypt everything.
