Newsgroup spam

(Spam Twitter)-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 18 January 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 on April 12, 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. 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.

Google Usenet News Archive

Unfortunately, the advent of the large Usenet archive kept as part of the Google Groups website, has made Usenet more attractive to spammers than ever. The goal in this case is not just to reach the members of a newsgroup, but to also take advantage of the fact that Google gives a higher pagerank to websites that are referred to by these messages, which are catalogued and mirrored in multiple languages at Google's top-level domain. Critics have suggested that Google has ulterior motives for "turning a blind eye" to the problem since the websites being pointed to use Google ads, which potentially generate revenue for both the spammer AND Google. The spam is extremely unfair to the companies paying Google and the spammer for an ad-click, as the most prevalent current spam (2010) is trying to trick readers into clicking on web ads by referring to them as images and saying that a link is hidden in them "due to high sex content" or that a link hidden in the image (Google ad) will take them to a "PayPal form" that will give them money.
