There’s a main heading that says the claims are a synthesis of unverified/unverifiable stories.

Really? Ctrl+F “unver” yielded nothing. Yet i saw some compelling arguments for deleting/renaming that page, but your denialism about the crimes of marxist-leninists against the people does not help your case for communism. Communism is power to the people, not power to psychopaths. The State is a bourgeois construct to protect the ruling class: the “worker State” is a myth.
