I think you're really overselling the risk here. At most any given kid is going to do this once, and the vast majority not at all.

Jesus, I never expected these responses.

Yeah, sure, do whatever I guess.

Is there any case where a kid calling in has caused serious harm or damage? I'll assume there's like...one, maybe.

More importantly, is there some kind of pattern of it that warrants...a response of some sort?

This sounds like kids getting poisoned from Halloween candy, which happened once from the kid's own parent.
