I agree 100%.  I have a script that converts the SBL and SPEWS listings 
into a Cisco ACL and we ignore them completely.  If they are going to 
list open proxies, it had better be a very short interval (I update 2-3 
times a week).  We use DNSBLs too, but the ACL approach is to deny them 
completely before they get started.
