General information about CRL

Added 22 Sept 1997 when Netzilla started injecting spam at CRL. Currently (April 1998) spamming porn ads to Alt.sexual.abuse.recovery.

These reports include both spam originating at Crl and spam advertising porn sites in the 209.60.206.* (Morgan Hill) netblock hosted by Crl. Crl is aware of both problems and seems to have no interest in dealing with either.

Crl may be reached by phone at 1-415-837-5300 or fax at 1-415-392-9000

General notes:

Only a small subset of usenet (261 groups) was sampled. Only articles that hadn't been cancelled yet were counted. Actual spam may have been much greater.
Heuristics that detect single-posted articles are, by their very nature, somewhat shaky. Innocent articles may be tagged as spam because they share certain characteristics or keywords with actual spam. In particular, a posted spam complaint that includes the spam in its entirety will very often be identified as spam.
Some posts may be forgeries intended to look like they came from CRL.
The first entry in the history file is not used to compute peak or average spam counts, as this entry covers an unknown number of days. This may cause an apparent disreprency between spam totals and spam averages.
