The DNC isn't a call blocker. Criminals, scams and illegal telemarketers will continue to call despite the laws. A lot of calls are coming from foreign country's as well. Spoofed caller ID's are used because they do not want to be found. Eventually they do though. Do consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.
Report your callers here, not just to the DNC alone:
