The global publishing platform Substack is generating revenue from newsletters that promote virulent Nazi ideology, white supremacy and antisemitism, a Guardian investigation has found.

The platform, which says it has about 50 million users worldwide, allows members of the public to self-publish articles and charge for premium content. Substack takes about 10% of the revenue the newsletters make. About 5 million people pay for access to newsletters on its platform.
