If you're in the position to report them, please report them.
Although this may be laughably funny to some of the more advanced users, the truth is that things like phone scams and phishing emails still exist because enough people do fall for them. Thus, please help shut these criminals down (and yes these are definitely criminals, not very different from those who would mug you and steal your cred it card).
I could not agree more. I feel sorry for the people who fall for such scams especially the elderly.
The problem is these people are using a Virtual PBX system with multiple call routing paths. Add to that the fact that there most likely using this system behind a VPN. In my case the calls seem to originate from New Jersey and Arizona. Theses calls could be originating from anywhere on the planet. Most likely they are from India or Pakistan. It would take a global task force to shut these people down.
I'm afraid the only defense is education on these types of scams.
