Basically just Peter Smollett. Like the list is some brain wormed and harmful shit, and clearly shows Orwell to be a racist, homophobic, anticommunist monster, but nobody in the British government gave a shit about the list, and the communists he actually managed to name were already pretty public about it except for Smollett. But the British government ignored the list so it didn't matter.

Like E. H. Carr and Isaac Deutscher weren't exactly secret about it. Carr was speaking on the radio about the need for an Anglo-Soviet socialist alliance, and Isaac Deutschers position on the matter had been known publicly since the early 40s. Same for most other communists he writes about. Other people he named like Kingsley Martin were anti communists, some were libs.

Orwell didn't snitch, or at least his primary thing wasn't snitching, that word gives him too much credit. Snitching implies you're aware of something and telling it to an authority who will use that information and Orwell did neither. He was an ignorant, racist, homophobic, anticommunist dipshit who wrote commentary on publicly avowed socialists, libs he didn't like, and people who had turned down his manuscripts, and handed it to the british governemnt who promptly threw it in the trash. At best he's an attempted snitch. Too much of a dumbass to properly snitch
