That's nice of them, to update the DB in a timely manner. Spamhaus
(imho) is one of the _extremely few_ lists "safe" to use. But this
lists idea can go very wrong, see the SORBS case, with big chunks of
IP space listed for years and for no reasons. In my experience they
too ask for money and it's clearly a scam of some sort. There are a
lot of scammers out there and the net if full of horror stories.
