The TikTok trend surrounding Agartha, a mythical utopia believed to exist within the hollow Earth, is increasingly normalizing white supremacist narratives among young users. A recent analysis by researchers at Neu-Ulm University of Applied Sciences in Germany examined over 43,000 videos related to Agartha, revealing that far-right actors employ various strategies to disseminate their ideologies without being moderated. These strategies include aesthetic camouflage, where extremist ideas are disguised within benign sci-fi tropes, and dog whistles, subtle symbols that communicate extremist views without attracting attention. The research also highlighted how extremists effectively use mainstream hashtags to connect with broader audiences, particularly through content related to fitness and self-improvement. The trend's reliance on absurd humor, such as AI-generated images of Adolf Hitler enjoying a popular energy drink, allows creators to blend extremist themes with mainstream culture, increasing their reach. This phenomenon underscores the importance of recognizing how extremist content can infiltrate everyday social media interactions, creating hybrid spaces where radical narratives can thrive.
