That may be true, but what does a provider do when they are presented with

for them to route, and that they have authority from the 'owner' to do
this... what is an ISP to do? Aside from route the blocks?
Just had a case today where a downstream "clueless" tier-4 ISP got a new
customer. The "clueless" customer wants his /24 to be announced. We asked
for proof of ownership. Clueless customer sends official letter to
clueless tier-4 ISP, who tells us "route it now!" We do a check in APNIC
and see it is part of a larger /19 assigned to someone else (probably
clueless's customer former upstream ISP). We told clueless tier-4 ISP that
we can't announce the /24. I am now waiting for an email stating "but
Bulbul ISP never checked APNIC, so why should you?"
These battles are won slowly and one at a time.
