As I once explained in a previous comment on another HN post -- https://news.ycombinator.com/item?id=33847117 -- I was involved in a political campaign that involved using fake profiles on Twitter and Facebook to boost news that favored the politician and attacked their opponents (I was a naive college kid then). The Twitter account still exists today.
Mind you, this campaign was a small operation in a third world country with less than two dozen people. Imagine what governments with millions to billions of dollars at their disposal could do. America's opponents can obviously not invade it or place sanctions, so they'll try to attack it wherever they can, and you can be sure they are doing it.
After my experience, I stopped paying attention or believing anything from social media. The majority of it are outright lies or half-truths, and I have not the time or strength to sift through them...not to talk of social media being outrage farming for the purpose of securing ad dollars.
