I wrote a piece years ago, when I was on Twitter, and called them Accelerants – people who seem to exist only to make conflict on social media nastier. And I think the really essential piece is this: no one cares enough about them individually to know how morally they act themselves, and so they can engage in moral censure of everyone and everything. If you are enough of a visible personality that people might track your history, people can respond to your moral judgments by pointing out areas where you yourself have failed to act morally, or at least, to areas where your moral beliefs appear to be inconsistent. But if no one cares about you enough to remember what you’ve said and done in the past, you’re free. And in the middle of a Twitter mobbing there’s so many low-follower accounts coming at people that no one could possibly respond to them all even if they cared enough to know something about them. They draw power from their powerlessness; they have the strength of a faceless horde. Facelessness, after all, means there can be no accountability.
