What's your (telephone) reputation?

Well, I knew this was going to happen eventually: Google now has global spam filtering for Google Voice. It works in a way very similar to how ISPs track the sending reputation of email senders based on feedback from their users (i.e. spam reports). Now, if you opt-in to Google Voice's new "Global Spam Filtering," calls and text messages from phone numbers determined to be "spammy" won't make your phone ring. They'll land in your Google Voice "spam" folder, out of sight and out of mind, until and unless you go specifically looking for them.

I think this a great idea -- collaborative reputation systems are cool. What do you think?


  1. I think its an awesome idea as well. What I'm wondering is: if folks (such as google, and/or others) wanted to publish such reputation data as a DNSBL, what the best way of doing so would be. I'd tend to think reversing the phone digits, as is done with E.164 (RFC 2916)
    and NAPTR (RFC 2915) .. would work well - but since telephone reputation is rather new, maybe there is a better way of doing so that could be used from the get go.

    Of course, publishing would only the first step; the ability to use such a resource within VOIP applications would be needed as well.

  2. I don't see it happening, because telephone service is so regulated. I'm sort of surprised Google even went this far. Clearly they made it opt-in out of concern that somebody would later sue them under those regulations, and wanted to make it clear that it was the end user's choice to block such calls.

  3. But that doesn't stop me from dreaming -- cause that would be really cool.
