NO *corporate* entity has EVER had ANY success WHATSOEVER in bringing down any service or p2p sharing that is run well and entirely within those networks. They are completely immune to DMCA, criminal or civil attacks.
No offense, but you are smoking crack. Onion sites get brought down all of the time. The Freedomhosting raid killed like 3/4 of the links on the Hidden Wiki. There are probably more FBI honeypots on TOR than there are "legitimate" kiddie porn sites, and they've had a pretty good run unmasking the users. Even the Silk Road got taken down and the owner thrown in jail. Keeping your site completely anonymous is incredibly difficult, almost as difficult as keeping it running at all on TOR it seems.
The Tao is like a glob pattern: used but never used up. It is like the extern void: filled with infinite possibilities.
