It's true that some carriers, in some countries allow you to port your number (though that's hardly everywhere, making the 'worldwide claim of this database the same be just an empty claim). So some 'things' have changed, just a little.
But, most importantly, 'Things' such as phone numbers, are still, to my knowledge, incapable of autonomous intentionality and even of having enough singular qualities for this company's mission to make any sense.
A phone number neither intends to do good or evil, nor does it have material components or specs to fail to carry out the user's intention and deserve a bad reputation.
Without these, the concept of reputation is simply inapplicable.
Until some number phone numbers started willingly or typically call the wrong place or person by intentional design or by poor design, this company shouldn't bother calling me. I suspect they should put their own number first on their own list of numbers being associated with *people* misusing numbers
