Yes that's the spirit!
I have seen some who subscribe to any RBL they come across. RBL providers
normally document their policies openly. So it is a good starting point to
decide whether the provider policies match your own policies.
Allen, to answer your question, I don't use RBLs. However my goal is not
that to scare anyone away from RBLs but rather to encourage educated
decisions.
