The last time accusation like that surfaces they were mostly fabricated. I hope bloomberg will check them for validity. They certainly do owe as much for their complicity of reporting on alleged interference.
I think it safe to say without much doubt that ZH is an extremely Pro Russian media outlet. Daniel and his father (Bulgarians) have been funded to some extent with Russian money and have ties to the Russian propaganda machine. I really am impressed they have been able to survive this long with all the shit they spew and the incredibly Pro Russian / Anti-American stance.
Do you have any specific examples of pro-Russian propaganda they posted? Legitimately curious.
I recall tons of it about a decade ago when I was an occasional reader.
They would even repost garbage from Sorcha Faal / David Booth, which is basically the same thing, but worse.
I made a joke on twitter about ZH being a Russian psyop, and now it's the one account I'm blocked by (that I know of).
