The US telecommunications network exists to support marketing, scam calls, advertisers, surveys, and fake surveys. All other uses have seemingly been deemed secondary, or a restriction of the spammers’ and scammers’ constitutional rights to program a computer to bulk-call the entire US population.
Call-blocking suggestions here? Short of sending all but known callers to voicemail, don’t bother. Those numbers are routinely spoofed. Which means even those “recognized“ callers can be scams.
In the US, call your Congressional folks, as they are the ones that have decided to allow this mess.
Email scams and messages phishing scams are also routine. I routinely get mail from a friend. Who died some years ago. Unbeknownst to that particular bunch of spammers that had harvested and are re-using our email contact information.
