Why is he scared of that? A lot of this reads like nerds LARPing, which is a really common theme in the rationalist community; they act like if their identity is revealed their life will be over, when they are usually random nobodies, that nobody except each other care about. I guess that whole bit makes a lot more sense if they're covering up child sex.
I love the guy complaining you can't go after them or you might be DOXED!! His description of the terrible "doxing" just sounds like shit we do all the time, lol.
