I thought 1.) There already is a “do not call” list and 2.) it’s about as effective as anything else the gov’t does. Which is to say, it’s not. I’ve gotta believe that people who are so bored and have so much free time that they answer telephone calls from numbers they don’t recognize must mostly be Democrats.
The do not call list is only good for so long. After that you have to renew it again. The best solution is to have audio caller ID. Certain phones like Panasonic come with it. Also specific ringtones for your cell or smart phone list do help. I do have a specific ringtone that I downloaded from ZEDGE for numbers that I do not recognize. When that comes on I do not answer the call and after I do an online search for the number I add it to my reject list
I’ve found do not call to be pretty effective. I went from multiple corporate calls a night to one or two a week. Except during election season since they exempted themselves.
