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 Dion.ne.jp.
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.
