[anti-abuse-wg] OECD report on SPAM

You have to be a bit careful about the underlying measurement
methodology.  In some European countries, most Internet access offered
to consumers reassigns a new IP address once a day.  (There are two
reasons for this: static IP addresses to differentiate business
products, and the drop in P2P traffic after IP address reassignment.
The latter is probably not very relevant today.)  Such daily IP
address reassignments can easily account for one or two orders of
magnitude of errors, depending on the observation period.

Disregarding feasibility etc., this would only be a short-term measure
because IP addresses will no longer be scarce ressource a year or two,
so the RIRs will lose any leverage they might currently have.
