It's run by a guy who literally did a nazi salute. One of their most prolific users is named "catturd". I'm astonished that anybody in research or science still remains there.

Edit to add: The owner of the platform contributed millions of dollars, endorsements, and manipulation of the platform to elect a regime which actively works to dismantle scientific and research funding and institutions. By continuing to use the platform, these people are contributing to the destruction of their work and careers.
