Months ago, YouTube pointed me toward a video that recommended Substack as a platform for some hobby. I made a public comment pointing out that Substack was profiting from spreading Nazi ideology. The YouTuber replied, said something like “No way, they’re not really doing that, are they?”

Maybe I’m naive, but I expected a YouTuber to be more terminally online than I am, to have heard of the Substack Nazi problem already. I also expected a YouTuber to at least Google “Substack Nazis” or similar before replying to some internet nobody. But apparently, no.

A lot of the coverage of the Substack Nazi issue that I’ve seen has been, broadly speaking, social media material, including blog posts. Those of us who read such stuff (like me, maybe you too) probably have some incorrect intuitions about how well-disseminated the ideas we find that way really are. Having a mainstream source like the Guardian pick up the story may be useful even if it doesn’t say anything new to us.
