Please read the documentation more carefully.
Scammers and spammers do not register ... they ignore the DNC list. Although there is a law against such cold calls, criminals ignore laws, right?
"Legitimate" telemarketers subscribe to the DNC list, and get updates every 31 days. They get their "subscription" by registering their business with the DNC people. The FTC sometimes call this by a different name ... "subscription" rather than "paid registration", but the subscribers must indeed register AND pay!
Recieved call today, no msg left. Caller ID shows "Charity". Lots of calls from Pennsylvania the last 2 months. Some are Fireman's Fund asking for a donation. They are not the "real" Fireman's Fund. Be careful. I blocked this number and reported to DNC.
I always report them and now I call up different agencies to report them.
So blocking them until they start calling with a new number then block that number and un block the old number.
Like I am going to give to an caller marked only as Charity, who never leaves a message or no one there when you do answer (which happens when you mistakenly think you know who is calling).
A guy continuously calls my phone number from this number 484-589-5619 Philadelphia claiming he is calling from the Police Fundraiser center. As soon as I answer the phone he acts like he knows who I am by calling me by my last name and then he proceeds to ask for my husband. I knew something was suspicicious about him because he sounded very wicked and aggressive. I told him not to call me anymore. The police department has no fundraising hotline so he is a LYING S.O.B.
