I have never heard of BlackBankMarket before, is it a silk road type of website? Is this latest story like when the admin of evolution stole everyone's Bitcoins and disappeared?
Yes, Black Bank was an illicit marketplace on the darknet (Tor), much like the Silk Road and Evolution.
It appears now fairly certain that the site has become the latest exit scam.
Is there any estimate of how many Bitcoins the guy running it has exit scammed with?
Someone once posted a link to a website that listed all the dark markets by the estimated number of Bitcoins going through them, but I can't remember the link.

Someone posted this link that gives a chart

There is a bit of debate about whether the chart shows percentages of listings or sales volumes, but it shows black bank had slightly over a quarter of evolution's market share.
