Matthew and all,
Yes, Google for some time now has been a haven for criminal use
and activity given it's own misconfigured DNS servers, and remains
so. Additionally the Whois listing for Google is in violation, and has
been
for some time no also. Yet Google, like Yahoo seeks to thumb their
nose at security and safety of it's users, which I am very decidedly
NOT one.
I believe ICANN has a contractual responsibility to bring Google
into compliance with RAA contract and policy requirements, but
likely will not do so due to their huge financial position in the
Global marketplace.
Of course we have been over this ground before and to little
or no avail.
