Security issues based on post RIR allocation rules

I'll simply endorse the 'stop judging an IP by it's RIR' approach. As a New Zealander (and APNIC is our RIR), having to convince  US institutions that our subnets should not be blocked simply because they're out of the same /8 as those used by other Asian nations with poorer IP address reputations , is a challenge because, well, a nation of 4.5M in the south Pacific is insignificant, right? :S

Also if the whole /8 doesn't sit within the same organisation or country, how is it smart to use it as any sort of differentiator?

Have banged my head against this one many times in my career to-date.

Mark.
