Re: Repeated Blacklisting / IP reputation

so... this thread has a couple of really interesting characteristics.
a couple are worth mentioning more directly (they have been alluded to elsewhere)...

        Who gets to define "bad" - other than a blacklist operator?
        Are the common, consistent defintions of "contamination"?

        If these are social/political - recognise that while the ARIN
        region is fairly consistent in its general use and interpretation
        of law, there are known varients - based on soveriegn region.

this whole debate/discussion seems based on the premise that there are well
known, consistent, legally defendable choices for defining offensive behaviours.
and pretty much all of history shows us this is not the case.

        (is or is not a mother nursing her child in public pornographic?)

So - I suspect that in the end, a registry (ARIN) or an ISP (COMCAST) is only
going to be able to tell you a few things about the prefix you have been handed.

        a) its virginal - never been used (that we know of)
        b) its been used once.
        c) it has a checkered past

and it will be up to the receipient to trust/accept the resource for what it
currently is or chose to reject it and find soliace elsewhere.
