What kind of info should you not present online?

Went down a rabbit hole of PSAs.

Just watched this video created by Children Of The Street Society and it had me thinking: https://youtu.be/DCtRjSSAPmM?si=SpX4YMdAKlsGRi7M

Obviously you shouldn’t put details like your home address, phone number, bank account etc but in watching the video you can see the person acting as the predator using info like their victim’s favourite sport team and paint ball activity that they posted about recently.

Could somebody seriously track you down from info like your favourite colour, your zodiac sign and other seemingly trivial info?
