[Usenet] The archetype and model of all good spam-fighters. Once upon a time, the 'Moose would send out spam-cancels and then post notice anonymously to news.admin.policy, news.admin.misc, and alt.current-events.net-abuse. The 'Moose stepped to the fore on its own initiative, at a time (mid-1994) when spam-cancels were irregular and disorganized, and behaved altogether admirably - fair, even-handed, and quick to respond to comments and criticism, all without self-aggrandizement or martyrdom. Cancelmoose[tm] quickly gained near-unanimous support from the readership of all three above-mentioned groups.
Nobody knows who Cancelmoose[tm] really is, and there aren't even any good rumors. However, the 'Moose now has an e-mail address (email@example.com) and a web site (http://www.cm.org.)
By early 1995, others had stepped into the spam-cancel business, and appeared to be comporting themselves well, after the 'Moose's manner. The 'Moose has now gotten out of the business, and is more interested in ending spam (and cancels) entirely.
