Still calling. If they know it's a scam and it has been reported to be so from channel 6 Maine then I would think they would be on to them to shut them down~! Geez
It's hard to shut down scammers. Even though the news reported that it's a scam, the phone number itself is most likely just a decoy, and NOT the number where the call is actually coming from. That makes it hard to track down without court orders to get phone records, and cooperation of not only the phone companies involved, but also many other authorities.
And, it costs money to do it, and time to go through with it. Money that news outlets may not have enough of to invest in, just to hunt down people making phone calls. The state can look, and probably is looking, into it, but since it is not directly or physically hurting people, it's not number one on the priorities list.
Yes, stealing people's information is causing harm. But, since they're not holding a gun to people's heads and demanding the information, or otherwise threatening people, no one is in immediate danger. This lets the state put it on the back burner to simmer while it deals with other issues (whether those issues are much more important or not is debatable).
