Re: "and they want to worry about/blame Russians!!??"
One of the most problematic aspects of this story is the fact that Twitter has deleted all the evidence. So now, if we want to check what, specifically, these accounts said - we can't.
This is a reflection of what makes Twitter (and other 'social media' platforms) much sneakier than conventional media. If something is broadcast on Radio Free Europe, anyone can record it, listen to it, play it back later - that means you know what was said, and you have all the information you need to counter it. But on Twitter or Facebook, there's no telling what a given person has been exposed to. It's hard to counter propaganda that you can't even see.
Doubly hard, of course, when your audience has been told that everything you say is lies.
