By your logic then, shouldn't algorithms be banned? If a U16 is going to turn to social media, and the feed is not in chronological order then how do we even guarantee that they will see what is happening in the moment when an algorithm is making the choice for them...
Seems more like, if they see something suspicious or are worried about it - dont go to your phone, just leave the situation as fast as possible. As usual, education and critical thinking is the answer.
