What company, organization, or otherwise operates and controls the
publically available Spews.org arbitrary block list?

Needless to say that the actual information provided by WHOIS lookup
is false:

domain:       spews.org
status:       production
origin-c:     chip@sendmail.ru#3
organization: Visit Lake Biakal!
owner:        chip level domains
email:        chip@sendmail.ru#3
address:      po box 61, Baikalsk-2
city:         Irkutsk region, -- 665914
postal-code:  665914
country:      RU
admin-c:      chip@sendmail.ru#3
tech-c:       chip@sendmail.ru#3
billing-c:    chip@sendmail.ru#3
registrar:    JORE-1

As can be seen from the above, the organization is listed as
"organization: Visit Lake Biakal!" which is obviously falsified. Also,
"email: chip@sendmail.ru#3" isn't even a legit email address to start,
but even removing the "#3" provides a non-operating email address and
in no way reflects what company or organization is controlling the
actual Spews.org arbitrary block list.

Taking a look at the IP of their website:
Name:   www.spews.org
Address: 216.65.63.103

So their ISP gave them 216.65.63.103.

OrgName:    Maxim
OrgID:      MAX
NetRange:   216.65.0.0 - 216.65.127.255
CIDR:       216.65.0.0/17
NetName:    MAXIM-NETBLK-1
NetHandle:  NET-216-65-0-0-1
Parent:     NET-216-0-0-0-0
NetType:    Direct Allocation
NameServer: PIT.MAXIM.NET
NameServer: PENDULUM.MAXIM.NET
Comment:    ADDRESSES WITHIN THIS BLOCK ARE NON-PORTABLE
RegDate:    1998-09-02
Updated:    2001-06-01

However, since this "Maxim" ISP has not delegated the IP to the actual
organization that is using it (even though it should under issuing
guidelines) this also provides no clue as to the actual operator.

And it is said that the company or organization that operates/controls
Spews.org views various newsgroups, but that obviously does not
reflect who actually operates it.

I'm certainly not looking for the above information or other vague
"rumours" or "maybes" in the answer. So the question remains...  What
company, organization, or otherwise operates and controls the
publically available Spews.org arbitrary block list?

The correct answer may also get a bonus payment if the information is
verified to be correct.

Hi,
Got this:
"Because other blacklist sites have been sued and shut down, SPEWS
(Spam Prevention Early Warning System) does not list contact details.
It is a nonprofit organization."

I'm believing it's run by a couple of individuals that have been very
careful in hiding their identities, why exactly do you want to find
out who runs it?
