Uh yeah, they did publish a list. Please be informed before you post. Publishing a piece accusing several well-known and established progressive news sites of being actual Russian propaganda based on one single anonymous, unverified source, who refuses to reveal a single thing about their methodology, membership, or funding seems like responsible journalism to you? (Not a single other journalist previously would touch this group, even Buzzfeed laughed at ProporNot). Sounds legit.
