To me there's a difference between the groups which can legitimately ignore the do not call list - politics, polls and charity - and the predators. Which is what telemarketing was to a degree and is now primarily after the do not call list. People in these jobs can quickly figure out they're doing borderline illegal work. I hang up on everyone, but I understand the hostility towards people who are taking minimum plus commission to troll for easy marks even worse off than them.
