Last year, I watched a series where a father searches for his missing daughter and develops a kind of system that works according to the algorithm principle. I remember that the users could post hints of all kinds, which had to do with the disappearance of his daughter, and the father of the track came closer and closer. He had probably also worked with the police to find other missing persons with the system.
I hope someone can help because I just can't find anything on the internet.
