It's not really light years. You will have to add at least the same amount for all other TLDs. And how do you want to get all of these data? Not all TLDs are available for zone transfers. > As I mentioned, the base problem has already been solved by whois.sc, And they also show the "base problem": they only list a fraction of what is really on that IP.

I think it's a massive effort and doesn't have much to do with spam fighting. You only want to use it in the end for spam fighting. The cost:benefit ratio of it is probably quite bad.
