Ironclad, let’s be real: If you’re seeing ads that make you nervous, trust your gut. They’re probably junk. And yeah, tracking someone without them knowing is a legal and ethical minefield. As for keeping tabs on your teen, those “Instagram trackers” are a bust. You’ll need something on their phone, but before you go down that road, have you considered just talking to them? It’s old-school, but surprisingly effective, and doesn’t involve potential felonies.
