That's because it's not an enforceable legal authority. You still need to
rely on the transparency of the member countries to enforce anti-spam
policy, pursue fraud, misrepresentation, extortion, etc.

That's right: just in case the IP address doesn't match in IP::Country
but the rDNS contains a country-code TLD (i.e. .mx).

The problem is that when matching against @bad_tlds you're don't know in
advance how many domain components to strip off and test... It could be an
arbitrary number.

So I'm taking a substring of the right-hand side of $hostname and
looking for
it in @bad_tlds, but I don't know in advance how long a portion of it...
