Reminds me of the best way I've heard to stop India's phone scams.
Blowhard US 'presidents' have threatened warfare over cyber-'hacking' since Jimmeh Carter. It's time for one to walk the talk. The Indian sub-continent has lost its 'civilization' pass.

The week after that, do the same to their telecoms: The week after that, lights out, country-wide.
