This moron ran a per-country/per-as blocklist in the early 2000s which 
was based on a DFZ BGP feed. I closed it off more than 10 years ago.

I just checked and I'm still receiving ~5 queries per second.

As per my anecdotal evidence, there are some really clueless operators
out there as well. There is, of course, the temptation to just add
a wildcard A record... But nah, I don't like hot places.

The other side-effect is that spammers are still very eager to use my
domain in their from: headers, judging by the amount of undeliverables
I receive (in waves).

Thanks,
