Ok, it's been tweaked.

I've changed @bad_countries to a hash, and I've changed @bad_tld's into
a hash
as well (I probe it with the RHS of the hostname from longest to
shortest, stripping
off the left-most component until there's only one component left).

Anyone else have any comments about the example or the strategy?
