I have to wonder, if a DNSBL were being operated entirely on a free

There are no large caches out there. That's not how DNS works in my opinion.
Obviously this negates the DNSBL's ability to try and pull cash out
of the larger entities, but purely from a resource management point
of view, if someone wants to offer a front-line cache for free,
surely that should reduce load.
It is expensive to provide such a cache for free. Why would someone
want to offer such a service for free?
