What your friend's daughter did—I know that most of my friends did that while I was still in high school, especially for Facebook. I remember trying to contact one of my friends back in the day and it was her parent that picked it.
I can imagine how your friend would have received numerous calls from different people.
I like the fact that we have algorithms in social networks, especially in TikTok, because it makes it easier for me to curate my contents from what I am interested in and the ones I don't. So my feed is always filled with educational contents that I don't feel I am dumb scrolling anytime I manage to find my way to tiktok.
