In that case.. it's difficult for anyone. It's still not any better for a state actor versus anyone else -- you've just upped the difficulty so high that it even includes state actors.

That is, (I believe) it is not possible to construct a nefarious deed that is harder for a state actor than an individual to execute. It is only possible to construct scenarios that are hard enough that both state actors and individuals cannot execute it.

A state can do anything a group can do, and a group can do anything an individual can do. They're supersets of one-another, in terms of capability and resource.

There is no "sounds perfect for a state-sponsored" anything -- everything is perfect for a state-sponsored entity, unless it cannot be done at all (because who has greater capability than a state? Other than a coalition of states, or even further, galactic nation-states)

>not true. in a truly organic network, where you actually know the graph back to you, it is very difficult for a state actor.

An entity with sufficient resources & time can probably defeat this -- the main thing is to generate more "accounts" or whatever;

need proof of id? Sufficiently good counterfeits.

need DNA proof? rob of a morgue.

users police themselves? make sufficiently "attractive"/fake accounts and add randomly until you get added by enough people, and then their friends, and then spam until you get blocked and do it again);

and hide them sufficiently well, faster than the governing entity(ies) can identify and remove them.

Sounds perfect for my galactic nation-state.
