I'd like to believe that our intelligence communities do, but I don't know.

What I do know that that Russian propaganda tries to "immunize" their marks against mismatching views. One method is to pull them out of the shared media ecosystem by seeding distrust against non-aligned media. Another is to associate any undesirable viewpoints with weakness, idiocy or perversion.

Last but not least, Russia already tested a complete internet disconnect of their country so they could isolate their own population from anything not state controlled, should the tide turn or an emergency happen.
