I really relate to this. My friend had almost the same scare when her daughter got a strange message from someone asking about her school and where she lived. Her first reaction was to delete the account, but we worked through the settings together instead. Making the profile private, limiting DMs, and switching off location sharing made a huge difference. They also tried uMobix as a quiet extra safety net for anything unusual. What mattered most, though, was explaining why those questions can be warning signs, so she could recognize them herself.
