TikTok has updated its efforts to reduce repetitive patterns of content that could be harmful, in addition to the new “refresh” feature. The app has been doing this for a long time, limiting videos that don’t exactly violate its policies but may have an impact on your viewing experience. Videos depicting sadness or extreme dieting and exercise are examples. If its systems detect a recurring theme in a set of videos, it actively replaces some of them with videos about a different topic. This can help to limit your exposure to content that may contain certain triggers.
