The DNC list only works for legit callers.  Several calling groups are exempt from the DNC.  Callers with the intent to defraud, scam or outright trying to rip you off have no intentions of using the DNC list for which it was designed to do.  Dial for dollars it's called!!   ADVF or American Disabled Veterans Fund, who called is a complete rip off!  Very little of the money raised goes to the purpose for which it claims to be!  Even legit groups have a hard time using the money for which it was intended for!  The new punch line is they are calling for a fake name and you answer the phone.  When you say Dave is not here, then the tone changes as well as the sales pitch!  Again if they were legit they would have your info and refer to you vs. some made up name!
