I'm sure that 99% of the US population would support a complete ban on robocalls... if only there was a congresscritter with the balls to sponsor such a bill.
You'd still get them as they'd exempt themselves.
We got rid of our landline as is was all robocalls (messages or autodial for the salesweenie to then talk to you). At election time the volume went up, WAY UP and 95% were for some politician looking to get elected/re-elected.
