Oh and let me add what TPB is really doing. They are playing with BGP, ASN's and routing tables to "hide" the location of their services. Simple WHOIS data is not enough to disclose their location as it's just made up, but they have to peer with someone at some point and these information are public. They do have a few different ASN of their own (like TPB-NET, PRQ etc), but they can only hide it far enough and everyone familiar with routing knows this.

Tor hidden service is only secure for end users, not to the service itself. While TOR admins say it should be secure, the attack vectors are fairly well known and USA has the means to discover the real ip behind TOR hidden services.

It seems like the whole TPB operation was fairly successful and the owners got to live the good life in Thailand (Neij) and Cambodia (Svartholm). They got tons of money to use on drugs (Svartholms drug problem was fairly well known in Cambodia) and living in the sun and beside swimming pools.
