How the FUCK do you "accidentally" make a toy that connects your kid to a phone sex line and sends them porn

I can answer this.

Randomly generated phone numbers, if given enough iterations, will eventually hit something real.

Remember the fake number in Squid Game that thousands called and it turned out to be some poor sap's home phone?

Of course, I could be wrong, but how many kids that age would have a phone? It's a stupid strategy if that was deliberate. Disregarding the ethical issues and all that, they're angling for a tiny minority of little kids who have their own phone + are curious enough to call the number on a toy?
