Same here. I have not publicised or updated my korea.services.net DNSBL for over a decade and it's still getting over 100 qps.

The vast majority of blockists are used by close to nobody, and only a handful are widely enough used to matter.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).
That's generally because they pick the To and From addresses in the spam from the same dusty spam lists.
