A Usenet newsgroup is a repository usually within the Usenet system, for messages posted from users in different locations using the Internet. They are discussion groups and are not devoted to publishing news. Newsgroups are technically distinct from, but functionally similar to, discussion forums on the World Wide Web. Newsreader software is used to read the content of newsgroups.
Spamming is the use of messaging systems to send multiple unsolicited messages (spam) to large numbers of recipients for the purpose of commercial advertising, for the purpose of non-commercial proselytizing, for any prohibited purpose, or simply repeatedly sending the same message to the same user. While the most widely recognized form of spam is email spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, online classified ads spam, mobile phone messaging spam, Internet forum spam, junk fax transmissions, social spam, spam mobile apps, television advertising and file sharing spam. It is named after Spam, a luncheon meat, by way of a Monty Python sketch about a restaurant that has Spam in almost every dish in which Vikings annoyingly sing "Spam" repeatedly.
The Usenet newsgroup alt.religion.scientology started in 1991 to discuss the controversial beliefs of Scientology, as well as the activities of the Church of Scientology, which claims exclusive intellectual property rights thereto and is viewed by many as a dangerous cult. The newsgroup has become the focal point of an aggressive battle known as Scientology versus the Internet, which has taken place both online and in the courts.
news.admin.net-abuse.email is a Usenet newsgroup devoted to discussion of the abuse of email systems, specifically through email spam and similar attacks. According to a timeline compiled by Keith Lynch, news.admin.net-abuse.email was the first widely available electronic forum for discussing spam.
A news server is a collection of software used to handle Usenet articles. It may also refer to a computer itself which is primarily or solely used for handling Usenet. Access to Usenet is only available through news server providers.
Sporgery is the disruptive act of posting a flood of articles to a Usenet newsgroup, with the article headers falsified so that they appear to have been posted by others. The word is a portmanteau of spam and forgery, coined by German software developer, and critic of Scientology, Tilman Hausherr.
Laurence A. Canter and Martha S. Siegel were partners in a husband-and-wife firm of lawyers who posted the first massive commercial Usenet spam on April 12, 1994.
An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived. Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes publicly visible.
alt.sex is a Usenet newsgroup – a discussion group within the Usenet network – relating to human sexual activity. It was popular in the 1990s. An October 1993 survey by Brian Reid reported an estimated worldwide readership for the alt.sex newsgroup of 3.3 million, that being 8% of the total Usenet readership, with 67% of all Usenet "nodes" carrying the group. At that time, alt.sex had an estimated traffic of 2,300 messages per month.
Newsgroup spam is a type of spam where the targets are Usenet newsgroups.
When a message is replied to in e-mail, Internet forums, or Usenet, the original can often be included, or "quoted", in a variety of different posting styles.
Google Groups is a service from Google that provides discussion groups for people sharing common interests. The Groups service also provides a gateway to Usenet newsgroups, both reading and posting to them, via a shared user interface. In addition to accessing Google and Usenet groups, registered users can also set up mailing list archives for e-mail lists that are hosted elsewhere.
The Breidbart Index, developed by Seth Breidbart, is the most significant cancel index in Usenet.
Crossposting is the act of posting the same message to multiple information channels; forums, mailing lists, or newsgroups. This is distinct from multiposting, which is the posting of separate identical messages, individually, to each channel,. Enforcement actions against crossposting individuals vary from simple admonishments up to total lifetime bans. In some cases, on email lists and forums, an individual is put under a stealth ban where their posts are distributed back to them as if they were being distributed normally, but the rest of the subscribers are not sent the messages. This is easily detected if the Stealthed individual has two different, and totally non-associated identities in the channel, such that the non-stealthed identity will see a different set of messages, lacking the posts of the stealthed individual, in their view of the channel.
A cancelbot is an automated or semi-automated process for sending out third-party cancel messages over Usenet, commonly as a stopgap measure to combat spam.
Conversation threading is a feature used by many email clients, bulletin boards, newsgroups, and Internet forums in which the software aids the user by visually grouping messages with their replies. These groups are called a conversation, topic thread, or simply a thread. A discussion forum, e-mail client or news client is said to have a "conversation view", "threaded topics" or a "threaded mode" if messages can be grouped in this manner. An email thread is also sometimes called an email chain.
Chris Lewis is a Canadian security consultant from Ottawa, who fought spam on Usenet and the early Internet. Active in volunteer anti-spam efforts in the late 1990s and early 2000s, Lewis was described in Net.wars (1997) as "the best known active canceler of spam and other mass postings" at the time. In April 1998, he organized an unsuccessful moratorium with forty other anti-spam volunteers in an attempt to boycott internet service providers into doing their share against spam. He worked as a systems architect for Nortel and, as of 2017, is Chief Scientist at SpamhausTechnology.
Control messages are a special kind of Usenet post that are used to control news servers. They differ from ordinary posts by a header field named Control. The body of the field contains control name and arguments.
Usenet, USENET, or "in full", User's Network, is a worldwide distributed discussion system available on computers. It was developed from the general-purpose Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980. Users read and post messages to one or more topic categories, known as newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are threaded, as with web forums and BBSes, though posts are stored on the server sequentially.
The Meow Wars were an early example of a flame war sent over Usenet which began in 1996 and ended circa 1998. Its participants were known as "Meowers". The war was characterized by posters from one newsgroup "crapflooding", or posting a large volume of nonsense messages, to swamp on-topic communication in other groups. Ultimately, the flame war affected many boards, with Roisin Kiberd writing in Motherboard, a division of Vice, that esoteric Internet vocabulary was created as a result of the Meow Wars.
