Interesting theory. It would also be a good way to subtly undermine the viability of news outlets, not to mention the insidious potential of altering snapshots at will. OTOH, I'd expect a state-sponsored effort to be more professional in terms of not threatening and smearing some blogger who questioned them.
If I were an intelligence agency wanting to throw people off my scent, maybe I'd set up or pay off a blogger to track down my site's "owner" and then do some immature shit in response to absolutely confirm forever that the blogger was right.
