No such thing. My rogue actor is the guy's on the other side of the fence goodie carrying the officially approved message.
Further to this, it is absolutely impossible to remove "rogue actors" without going full Brezhnev and exercising to the minute control on the whole media to carry the "soviet state message". This is because every piece of media now has some level of social aspect - discussion forums, facebook integration, google news integration, twitter integration. You name it.
In fact, even Brezhnev failed at the control bit too. There was a physics joke floating around Moscow during the darkest days of the Gerontocracy: "Is the Theory of Relativity valid? Of course it is not. It has been experimentally proven that rumours travel at faster than lightspeed".
The "platforms" Ginnie is moaning about are today's rumour mill. They are simply the medium in which things travel instead of watercooler conversations and phone gossip. If she wants the travel of information on them curtailed, she can have a look at how successful were Brezhnev, Suslov and Honeker in doing so.
