I'm surprised to see that Ulbricht thought government issued id was the viable solution to the spam/troll/infiltrator problem on the dark web. I would have expected more experiments with reputation based systems and blockchain based identity (such as namecoin). But identity is hard, I get that. Probably the hardest problem these sites face. (Just for curiosity's sake, does anyone with a bit more insight know if collecting passports is a common occurrence in other dark markets?)
