Honestly, these are actually already aggressive RBLs with false positives. I would never blacklist directly from these without any further verification. For me, the only safe ones are relays.ordb.org and dnsbl.njabl.org. Because these only list proven openrelays and there is a way to be removed from these when the problem is corrected.
