That is smart. Compare this with Wikipedia which blocks entire IP
ranges, and unfortunately my dial-up (Vodafone Wifi in a pretty
crowded, for European standards, place) is one of those. They did
not even allow you to log in (some years ago).
Immense amount of spam you have. I only use the mentioned plus
a local bogofilter instance that learns for some years, and i (do
not want to knock on wood) have around one or two dozen each day,
of which less than a handful is not auto-detected, but most of
those are "maybe", so.
Back to the island.
