I can't give you a NOC contact, but I can perhaps fill in some of the
routing history of the situation.
Using GRADUS (http://gradus.renesys.com), I identified the networks from
your description (hopefully the right ones :), looked into the patterns of
advertisement, and reconstructed the timeline (all times GMT).
None of these blackholing more-specifics were being advertised before
19th November 2002. The sequencing of events suggests to me that all six
networks "belong to" and are being managed by a single organization.
Someone from BBN may be able to shed more light regarding the "ownership"
of the 220.127.116.11/24 subnet.

First route. Genuity starts originating 18.104.22.168/24, and
continues to do so for 51 days.
22 Nov 2002 (18:11)
Supernet starts originating 22.214.171.124/22.
02 Dec 2002 (20:03)
Supernet starts advertising 126.96.36.199/24.

Supernet starts originating 188.8.131.52/24.

Genuity abruptly stops originating 184.108.40.206/24, leaving

Supernet takes over origination of 220.127.116.11/24 as well.
15 Jan 2003 (13:26)
Supernet starts originating 18.104.22.168/24 and 22.214.171.124/24

Your customer starts advertising the full legacy B space (126.96.36.199/16),
single-homed out of AS26797. It has not been routable to this point.
22 Jan 2003 (17:00)
AS2116 starts advertising the /16 as well. SuperNet is now blackholing
your customer by advertising the six more-specifics.
