1. We don't have any information yet, whether this was an automated ban, or something else. Due to the high profile I imagine we will find out soon, so all the hysteria in this thread is a bit premature
2. Ironically, what this account is doing is basically doxxing, whether the data is publicly available or not, it certainly makes it easier to track someone who has plenty of enemies.
3. If it was banned under Musk's instructions, that is pretty hypocritical after his tweet 2 weeks ago, but I still think it's a bit ridiculous to cite free speech issues being violated here when this is easily argued as a doxxing case.
