Perspective on ARIN allocations to non-American entities

[Brian Wallingford <brian () meganet net>]

I've searched the IANA and ICANN sites, and have found no justification
for what appear to be ARIN allocations to foreign entities within
66.231.

Two serious UCE/hacking attempt offenders are as follows:
 66.231.64.0/20   GIGA-BLK-1
 66.231.128.0/20  ECON-BLK-1

Both of which appear to be completely unapologetic for their users'
activities and refuse to take any action against repeat offenders
(10's of thousands of attempts per week here).  Why have these blocks
apparently been allocated via ARIN?

Am I missing something?

Cheers,
Brian
