The do not call list is a joke. It doesn't do a damn thing for anyone except give scammers and telemarketers a central place to get phone numbers of people to harass and [***].
Repeated unsolicited calls - I am also on the Do Not Call list, but they ignore this. No teeth in the DNC List unfortunately. Start the fines at $1Million for the first spam call and go up from there. The problem would stop overnight.
