I have also spoken to someone who knows Sartre in real life.
They told me that Sartre is a 33rd degree Freemason and had to disappear for a while for the Bilderberg conference 2023 which is happening in a few weeks. They are planning the next "big event", and because he controls so many niche AI sites, he needs to be there so they can plan how to use AI to further enslave the world. This person told me he does this every year, and will re-appear in June once the conference and surrounding events finish.
I wouldn't be too worried about him, I trust this person because they showed me some photos of them and Sartre together at a Freemasons lodge, there is no way these photos could be fake.
