Head of LessWrong and generally active rationality community leader here. Happy to answer any questions people have. These people haven't been around the community for a long time, but I am happy to answer questions with my best guesses on why they are doing what they are doing.
They've been banned on LW and practically all in-person things for like 5+ years now. My guess is the reason why they hung around the rationality community this much years ago is just that it's a community with much higher openness to people and ideas than normal, especially in the Bay Area. IMO in this instance that was quite bad and they should have been kicked out earlier than they did end up getting kicked out (which was like 4 years ago or so).
