In The recent case where dutch police seized one website and also after the seize of silk road one some sellers got arrested. How do you think this happened? I mean seller for sure didn't give their name or location, mostly possible that buyer's name are recorded with the shipping address if they didn't use pgp. So how do you thin sellers have been caught? Something a about bitcoin transfers? How can a bitcoin transaction be tracked?
Nod: he got caught b/c of some package intercepted en route to Alaska. They feds then began to look for similar packages and saw that they were coming from Seattle. They alerted the Seattle area post offices, and when Nod went to the post office, a PO worker got Nod's license plate #, and that was all she wrote.
MDPro: She was a lousy vendor in terms of security. The feds simply made a few purchases from her and she was dumb enough to use a return address that was a private mailbox that was easily traced to her.
Supertrips: He had a shipment intercepted in customs. They profiled the package and quickly began to intercept his shipments. He left a fingerprint on a package. The FBI sent the prints to Europe. He must have been arrested in the past, b/c one of the European countries identified his print from their database. His partner in the U.S.- Underground Syndicate, was arrested, but I haven't seen any details. He probably flipped and lured Supertrips to travel to the U.S. and he was arrested as soon as he arrived.
