As for blocking list, I know about the limitations. More specifically, it's not non-profits in general that are exempt, it's *charities*. Not all non-profits are charities.

Even those sorts of groups are supposed to honor requests to put you on their do not call lists.

Which is one of the reasons for my proposal. If it's a robot caller, there's no way to *tell* them.

And for political calls, there's a need to be able to *positively* identify the origin of the call (because of dirty tricks campaigns)
