TikTok is used by young people because they can find entertainment, information and connections there. However, a new report by jugendschutz.net shows how easily they can fall into extreme or populist echo chambers. Part of the problem is TikTok's suggestion algorithm, which shows users more and more content of the same type - including extremism, disinformation and conspiracy theories. An entire network of content creators is taking advantage of these platform dynamics, as the report shows. This also has an impact on young TikTok users. Motivated by increasing reach and positive feedback from extremist communities, they are increasingly posting radical content on TikTok themselves.
