Newsgroup spam

Newsgroup spam is a type of spam where the targets are Usenet newsgroups.

Spamming of Usenet newsgroups actually pre-dates e-mail spam. The first widely recognized Usenet spam (though not the most famous) was posted on January 18, 1994 by Clarence L. Thomas IV, a sysadmin at Andrews University. Entitled "Global Alert for All: Jesus is Coming Soon", it was a fundamentalist religious tract claiming that "this world's history is coming to a climax." The newsgroup posting bot Serdar Argic also appeared in early 1994, posting tens of thousands of messages to various newsgroups, consisting of identical copies of a political screed relating to the Armenian Genocide.

The first commercial Usenet spam, and the one which is often (mistakenly) claimed to be the first Usenet spam of any sort, was an advertisement for legal services entitled "Green Card Lottery - Final One?". It was posted in April 1994 by Arizona lawyers Laurence Canter and Martha Siegel, and hawked legal representation for United States immigrants seeking papers ("green cards").

Usenet convention defines spamming as excessive multiple posting, that is, the repeated posting of a message (or substantially similar messages). During the early 1990s there was substantial controversy among Usenet system administrators (news admins) over the use of cancel messages to control spam. A cancel message is a directive to news servers to delete a posting, causing it to be inaccessible to those who might read it. Some regarded this as a bad precedent, leaning towards censorship, while others considered it a proper use of the available tools to control the growing spam problem.

A culture of neutrality towards content precluded defining spam on the basis of advertisement or commercial solicitations. The word "spam" was usually taken to mean excessive multiple posting (EMP), and other neologisms were coined for other abuses
