The DNC list can't "prosecute". Breaking the Do Not Call law is a civil offense, not criminal, so there's no "prosecution". They can file a law suit and do so several times a year. But with the limited staff assigned to DNC violations (I've heard it's about 30 people) and the difficulty of tracing VOIP phone calls (one case took about a year, over two dozen subpoenas and over $100,000 to pursue), only the biggest offenders will ever get nailed.
Called today at 10:15 AM. Left no message. I don't know anyone from Garden City, NY. Blocked. Previously, I was getting a flurry of no caller id calls (2 today and 3 yesterday). Of course I don't answer. I'm just going to reject them everytime on my iOS.
