Summary
The Blackout Challenge is a dangerous internet trend, also known as the choking game, which involves intentionally depriving the brain of oxygen to achieve a brief euphoric state. It gained significant widespread attention on TikTok in 2021, primarily targeting children and adolescents, and has been linked to the deaths of at least twenty children. This challenge has been compared to other harmful online trends and hoaxes. A landmark court ruling in the case of Anderson v. TikTok, Inc. and Byte Dance, Inc. determined that TikTok's algorithms are not protected by Section 230 immunity in a lawsuit filed after a child died participating in the challenge, suggesting that algorithmic content curation may be considered editorial judgment and could alter platform liability.

Now, the Third [...] The court held that TikTok is not merely hosting third-party content but actively recommending specific content to users, transforming it from a passive platform to one engaging in “expressive conduct.” TikTok’s algorithm, according to the court, isn’t simply displaying content but making targeted recommendations that can influence user behavior — including a ten-year-old child’s decision to try the “Blackout Challenge.” This shift marks a critical distinction: while Section 230 protects
