Nonsense. The mere fact that a listing on one DNSBL is absent on others doesn't make it "questionable". Many DNSBL operators have in fact been working to decrease overlap amongst lists in recent years. If everyone listed the same IPs the world would do with a single DNSBL, mirrored everywhere for load.
