The fact that people use some of the ridiculous RBLs out there indicates
that there are still quite a few boneheads out there, and I'd be willing
to bet that they outnumber the clued ones.

You'd be suprised at how many times I've come into a consulting situation
and had to explain to executives that their problems came from some admin
using blacklists with high casualty rates and irresponsible practices
(SPEWS/etc). But hey, it gives me lots of consulting opportunity, so I
guess I shouldn't complain too much.

Every time someone gets fired/reprimanded for using SPEWS or some other
kind of list, I'm sure one more person springs up to fill their place.
