In what jurisdiction would I be liable for verbally harassing a scammer?

I ask because worked for a cybersecurity firm and we would, on occasion, and mostly the “teh lulz” screw with phone scams. Our legal had nothing to say on that front.

In many countries, harassment of any kind is illegal, regardless of the reason or if it involves a protected class or not.

The scammers would have to take you to court. Something about throwing stones in glass houses comes to mind as relevant here.
