I find that most admins that decides on RBL lists are well educated about what lists they choose to use are (the end-users are however not always well informed about it and that is where most of the complaints are coming from).
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.
I suspect that BGP admins are by their nature even better educated and will likely do even more research prior to using anything.
Don't be so sure of that either; I regularly find poorly configured routers redistributing default, loads of /24s and even /30's into their neighbors.
