I see your point, but that would require everyone to register with e164.org (or similar), which is fine when the entire world has transformed into VoIP. But until then, there's going to be a lot of false hits using your method.

I generally feel blacklists are easier to maintain than whitelists as they are less restrictive and if these blacklists are shared (like SBL's) we will all benefit from it. The question is though, is this the right way to go ??
