Well, it depends on what you're trying to obfuscate.
Suppose Joe goes to an "IP leaser" and claims to be a particular
ARIN-registered org. Joe gets IP addresses which he controls and
announces them from a "bulletproof hoster" from which Joe proceeds to
distribute child porn. As SWATting goes, it's a bit on the pricey side
but it's not inconceivable.

Same. Additional questions for ARIN are:
1. Has this happened to an ARIN registrant?
2. If yes, how many times is ARIN aware of it having happened to an
ARIN registrant?
We can sit here and dream up all manner of ways to abuse the ARIN
process, but at the end of the day security is a cost/value
proposition. If delta threat x delta vulnerability x incident cost is
less than the implementation and operational cost of the proposed
security then it shouldn't be done.

I like this approach much better than the whole screwy "domain lock"
thing they do with the DNS.
