when you're offering a service designed to expose a list of numbers, there's no way to design it in a way that doesn't expose that list of numbers. given enough time, a motivated person will extract all the data. most likely, this page started out as a list of all 74k phone numbers, and at some point somebody built a lookup tool on top of it. there's no reason to assume that keeping the full list secret was ever a design goal.
