Almost like he's doing this to scare people away from criticising him.
That's all it is. He chafes at any criticism (real or perceived), so one of his tactics is to call his detractors cowards if they don't let him doxx them (or does anyone really think he is going to add every random internet person to "THE LITIGATION"? lol). This is one of the things that makes me wonder if he even has a lawyer, much less a "legal team." Any lawyer worth his salt would have sat him down by now and made clear that if he didn't shut up, he would be representing himself.
Unless he ended up with a lawyer who figured him for an easy mark, and will spend as little time as possible working on the case while finding ways to charge him for "research" or whatever other line items he can dream up.
