This is http://keithlynch.net/toll.html

I am no longer maintaining the list of toll-free numbers seen in
recent e-mail spam.  The numbers were not getting enough calls to
justify the large amount of time and effort I put into keeping the
list accurate and up-to-date.  If you want to start a similar page of
your own, please tell me, and I'll link add a link to it from here.

I am still maintaining the following list of toll-free numbers of
various sites such as AOL, Compuserve, Genie, Netcom, AGIS, ACSI,
Digex, etc.  These are mostly ISPs and NSPs, or the employers of
frequent news.announce.net-abuse.email posters.  This list can be used
to find the phone number of a spammer's upstream provider to complain
to.  It can also be used to identify unknown numbers seen in spam or
in anti-spam newsgroups.  Please don't call these numbers unless you
have been spammed by one of their customers.
