Substack has industry-leading newsletter tools and a platform that independent writers flock to, but its recent content moderation missteps could prove costly.

In late November, the Atlantic reported that a search of the publishing platform “turns up scores of white-supremacist, neo-Confederate, and explicitly Nazi newsletters on Substack—many of them apparently started in the past year.” That included 16 newsletters with explicit Nazi imagery, including swastikas and the black sun symbol often employed by modern white supremacists. The imagery appeared in prominent places on Substack, including in some newsletter logos — places that the kind of algorithmic moderation systems standard on traditional social media platforms could easily detect.
