To that end, you start examining concepts like DNSBLs, like Ben
suggested. You can even make those pay-for-access with reciprocal data
sharing agreements if you get beyond a particular corpus size; that
would help reduce the amount of junk data that gets in.

*None* of this would work against the Obama campaign's final push:
They crowdsourced their robocalling by giving their supporters numbers
to call. At that point, you're stuck with call screening and/or
whitelists.
