I think almost certainly that disinformation based on fake accounts simply posting memes or targeted viewpoints, hoping to send the message through sheer repetition, it still a lot more common than doctored factual information. (Not that that means that faked up disinformation isn’t a problem - just saying I think it’s still relatively rare as a vehicle for disinformation.)

Why would you even open yourself up to “see, the underlying citation for this thing they’re saying is not true” when you might as well not even enter into the sphere of backing up what you’re saying with facts, and just state your assertions as if they were facts, instead.
