There are so many government officials on Twitter, and causing any number of them to tweet something plausible but untrue could be a big deal - from moving markets to moving troops. Just imagine if Donald Trump's account tweeted that Antifa should be shot on sight. I'm certain people would die because of that. Or, perhaps slightly less plausibly, that Boris Johnson tweeted that he's had enough and is abandoning negotiations with the EU. That would cause a frantic reaction from the markets before any official statement could be put out.
