I'd say for a mob it may even be understandable (if you decided to roll with us, you're in for a full trip), we are talking about deeds after all, not empty words.
But the empty words now result in people being fired and blacklisted, with as little effort as writing a sentence or a retweet. The mob doesn't even have to be in the same ballpark as truth. The worse thing is these things are picked up by newspapers trying to tap into social and making them "the official record".
same as it ever was, now with a lot less effort from the mob
