No, that caught them because they were careless. Ross linked Silk Road to his meatspace email address in posts to Bitcoin Forum. And misconfigured Apache to leak Silk Road error messages via clearnet. And kept personal information about his staff on a laptop (albeit LUKS-encrypted) that he used in a coffee shop, and at at public library. Also chat logs, and a comprehensive diary.
