It will require TOR or similar systems though, otherwise each federated instance transporting some content that is deemed illegal will be targeted. Authorities can't win the war, but they can make the damage for individual targets very large, thereby making most people shy away from it at all, like they are doing for TOR exit nodes in many jurisdictions.

But once it's on TOR, it'll be similar to the DNMs for drugs: once it's out of the bag, you can stamp out individual sites, but the system is there to stay.
