Yeah it isn't like they could have I dunno. Loaded bitcoin with WU with a fake ID via an exchanger in Russia, sent it through a mix, cashed it out to pecunix, bounced it to liberty reserve through an online casino, cashed it out to an anonymous domain name registrar in some third world country through a different exchanger and have a random name with no tie to them in the Whois? Seriously do you think they are so retarded as to ever have their real name anywhere near the hosting or domain registration?

Second of all, oh no the FBI might get the hidden service!! Well that isn't very hard considering they could just add some nodes to the Tor network and open an infinite amount of circuits to the hidden service then send a pattern of modulated packets over the circuits until they detect that pattern going to the entry guard. Detect all of the entry guards and then compromise one to find the hidden service. Tor hidden services are better than nothing but they are not that anonymous, although clients are.

But the thing is why would the FBI do this attack to locate the hidden service (assuming they even can which is doubted since they are a bunch of noobs who can't even trace CP hidden services with the same attack) to locate a server that has nothing but asymmetric encrypted orders on it?? Compromise of the hidden service, although not that difficult to do, is of close to zero benefit to an attacker.
