it occurred to me, on reading Ted's note excerpted below, that so identifying
IPv4 blocks that ARIN believes but can't yet prove are abandoned is a
wonderful invitation to hijackers--increasing the likelihood of one thing
you're trying to prevent, while working on another goal of disputable value
which is coattailed to a goal of undisputed value.  I believe it's fine to
clean up WHOIS data, and even trying to scrape up every last dreg of
available v4 space is useful, but it's not going to stem the tide of runout,
nor will the small relief it offers arrive in time.

| SO what we will end up with this policy is the following:
| a report from ARIN that lists the reclaimed prefixes, and the ones
| "in dispute" ie: the ones where verification is pending.  Those will
| be visible in WHOIS by the existence of a "bogus e-mail" mark on
| the e-mail data in the POC.  We will know that a certain percentage
| of the "verification pending" ones will turn out to be reclaimed,
| and so based on that we will be able to make a pretty accurate estimate
| of how much stale IPv4 is tied up in WHOIS.
