Suggested new language:

Inevitably, some of these listings may impact non-abusive messages --
or, in the case of a DNSWL, may permit unwanted messages.  For some
lists, such impact is both intentional and desired.  Either way, this
has resulted in some people labelling such practises by the emotionally
loaded term "collateral damage".  It is entirely incumbent upon the user
of a DNSBL (or any other filtering technique) to find the appropriate
balance of potential risk and potential benefit for their own
environment.

(This last paragraph repeats things said elsewhere in the document
already, but it may be worth repeating.)
