This article explores the mimicking of tabloid news as a form of covert racism, relying on the credibility of an established tabloid newspaper. The qualitative case study focuses on a digital platform for letters to the editor, operated without editorial curation pre-publication from 2010 to 2018 by one of Denmark's largest newspapers, Ekstra Bladet. A discourse analysis of the 50 most shared letters to the editor on Facebook shows that nativist, far-right actors used the platform to disseminate fear-mongering discourses and xenophobic conspiracy theories, disguised as professional news and referred to as articles. These processes took place at the borderline of true and false as well as racist and civil discourse. At this borderline, a lack of supervision and moderation coupled with the openness and visual design of the platform facilitated new forms of covert racism between journalism and user-generated content.
