After Substack shocked an unknown number of users by sending a push notification on Monday to check out a Nazi blog featuring a swastika icon, the company quickly apologized for the “error,” tech columnist Taylor Lorenz reported.
“We discovered an error that caused some people to receive push notifications they should never have received,” Substack’s statement said. “In some cases, these notifications were extremely offensive or disturbing. This was a serious error, and we apologize for the distress it caused. We have taken the relevant system offline, diagnosed the issue, and are making changes to ensure it doesn’t happen again.”
Substack has long faced backlash for allowing users to share their “extreme views” on the platform, previously claiming that “censorship (including through demonetizing publications)” doesn’t make “the problem go away—in fact, it makes it worse,” Lorenz noted. But critics who have slammed Substack’s rationale revived their concerns this week, with some accusing Substack of promoting extreme content through features like their push alerts and “rising” lists, which flag popular newsletters and currently also include Nazi blogs.
