Of course, and I entirely agree, but many have found that the sharing of
particularly effective combinations of DNSBLs to be useful -- but always
with the caveat that the de/listing policies and operation must be
carefully considered by any administrator who is considering using any
particular one.
Added to that is the fact that DNSBLs come and go, and maybe there are
newer ones around these days that may prove effective that those who
already have an established DNSBL combination may wish to consider.
