Farbman was in New York in 1918 as correspondent for Maxim Gorky's Novaya Zhizn pro-Menshevik newspaper, and wrote to oppose the Allied intervention in the Russian Civil War.
Returning to Russia he was one of the first correspondents with connections to the British Press to cover the early stages of the Russian Civil War.
He published a number of books on post-revolution Russia and his study on the first five-year plan was particularly popular in the United States.
Farbman wrote in the British press to urge the public to support the revolution, which he characterised as largely moderate, and to claim that the events had strengthened Russia as an ally in the First World War.
[5] He returned to London in July but was back in Russia for the winter of 1917–1918, a key period in the Russian Civil War that followed the October Revolution that brought the Bolsheviks to power.
[7] A reviewer for the Evening News said "I would make Michael S. Farbman's Russia and the Struggle for Peace compulsory in all schools ... we here learn the actual truth for the first time about the Revolution".
[14] In 1940 Farbman was mentioned in the United States Congress by Representative for Montana Jacob Thorkelson as a possible "subversive" who had operated in the West.
