I notice that there is no sign of stopping congresscritters, or the survey-takers in their employ, from robocalling. Since that's the vast majority of robocalls that I get I doubt that this is going to make any change in my life.
FYI, it's not enough to tell a phone caller to take you off their list. You need to say, "Put me on your Do Not Call List." They're required by law to do so, and any time they sell or rent their phone list the DNC list is required to go with it. If they tell you they're not required to have a DNC List because they work for some slimeball pretend non-profit that does political work I've found that the following technique works. Say, "If I were to cuss and swear at you then you would put our number on a list of people not to call again. Please put our number on that list." Those two simple changes changed the number of calls that an acquaintence got from 7-8 a night to 7-8 a week.
If you're ever required to put down a phone number, for store discount cards or something, use the same number that I (and a hundred other people do). (321) 123-4567. You'll be amazed at the number of cashiers that think it's really your phone number.
