I bought a "Zapper" a fews years ago.
It produces a signal that indicates to the calling computer that the number dialed has been disconnected.
Those calls that get through are handled appropriately.
I always ask the caller why they are insinuating that I am dumb.
They always come back with "I'm not insinuating that you are dumb, sir, all I am doing is....."
My reply goes along
"Well, don't you think that if I was in the market, I can do my own research and make a decision without your assistance? Evidently not if you are calling me, so, Yes, you are insinuating that I am too dumb to do it on my own. And if you insult me in such a manner, I have not choice but to report you and your business as harassing and insulting me. (Now, please send me your name and address so I have the correct information for the lawsuit.)"
