ability to submit phone number to do not call list
We need an API that accepts a phone number to add to the Do Not Call list. It would also be nice to be able to report offending telemarketers.
This would belong in an FTC database (unless the FCC handles the wireless calls?), and as I'm sure you're aware if you have a land line, is barely enforced even with complaint. Your best bet is to get your telcom to not peer with the offending telcom.... Oh wait, there's only really one telcom these days isn't there. I guess you'll do best with answer captchas or a voice hashcash service.
