Well yeah, it’s no secret that TikTok had a white supremacy problem. There was a researcher who discovered that they could make a brand new account and (by only interacting with certain types of content) get white supremacists on their For You page within 20 minutes. Algorithmic feeds are funny like that, because they just gauge engagement. The algorithm isn’t making any moral decisions on whether the engaging content is socially acceptable. For better or worse, it just goes “this person likes this content, so I’ll show them more.”
