AI systems that remove harmful content often do not understand most African languages. This matters because these systems decide what stays online and what is taken down for many users across the continent.
A 2025 study found only 42 African languages appear in major language models, and just four are handled with consistency: Amharic, Swahili, Afrikaans and Malagasy. Because English data dominates, systems can remove posts without clear explanation or fail to spot harmful content in local languages.
Researchers and groups in Africa are building datasets and models, and new rules in Europe and national strategies may push platforms to improve moderation.
