I have a friend who has a site called "arrestwanted.com".  It never really took off with people who use paypal.  Maybe it could work in the cryptocommunity....
What if we accepted all cryptocurrencies, but stored them as a basket of bitAssets?  I bet we could get enough cash from the entire cryptosphere to get a high-dollar firm to put some of these people in prison.  What do you think?  Maybe the chilling effect can go both ways??
