Dave The Resurrector
Dave the Resurrector was a so-called "resurrector bot" that responded to any attempts at canceling a message on the usenet newsgroup news.admin.net-abuse by re-posting the message. Ohm, Paul K Skirvin, Tim It was written by Chris Lewis. The bot is notable as one of the first escalations in the spam arms race.

Internet Bot
An Internet bot, web robot, robot or simply bot, is a software application that runs automated tasks (scripts) over the Internet, usually with the intent to imitate human activity on the Internet, such as messaging, on a large scale. An Internet bot plays the client role in a client–server model whereas the server role is usually played by web servers. Internet bots are able to perform tasks, that are simple and repetitive, much faster than a person could ever do. The most extensive use of bots is for web crawling, in which an automated script fetches, analyzes and files information from web servers. More than half of all web traffic is generated by bots. Efforts by web servers to restrict bots vary. Some servers have a robots.txt file that contains the rules governing bot behavior on that server. Any bot that does not follow the rules could, in theory, be denied access to or removed from the affected website. If the posted text file has no associated program/software/app, then ...

Cancel Message
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. There are two historical alternatives to header field Control. They are not supported by contemporary software and forbidden according to RFC 5537. However, the traditional format of the subject line is widely used in addition to the Control header: the subject line consists of the word "cmsg" followed by control name and arguments. Types cancel A cancel message requests the deletion of a specific article. The body of the Control field contains one argument, the Message-ID of the article to delete. According to RFC 1036 only the author of the target message or the local news administrator is allowed to send a cancel (cancels not meeting this condition are called "rogue cancels"). To verify authorization the line (or line, if it exists) of the cancel message must mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Usenet Newsgroup
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. Before the adoption of the World Wide Web, Usenet newsgroups were among the most popular Internet services, and have retained their noncommercial nature in contrast to the increasingly ad-laden web. In recent years, this form of open discussion on the Internet has lost considerable ground to individually-operated browser-accessible forums and big media social networks such as Facebook and Twitter. Communication is facilitated by the Network News Transfer Protocol (NNTP) which allows connection to Usenet servers and data transfer over the internet. Similar to another early (yet still used) protocol S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chris Lewis (Usenet)
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. Career Lewis worked as a senior security architect at Bell Northern Research, then as a systems architect for Nortel from 1991 to 2012. In 2002, Lewis led a five-man spam-filtering team at a major telecommunications company with over 45,000 employees. His unofficial title was "spam issues architect", and he was conservative with the messages he filters so as not to accidentally hide potentia ...

Spam (electronic)
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 (especially the fraudulent purpose of phishing), 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. Spamming remains economically viable because advertisers have no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cancelbot
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. History One of the earliest uses of a cancelbot was by microbiology professor Richard DePew, to remove anonymous postings in science newsgroups. Perhaps the most well known early cancelbot was used in June 1994 by Arnt Gulbrandsen within minutes of the first post of Canter & Siegel's second spam wave, as it was created in response to their "Green Card spam" in April 1994. Usenet spammers have alleged that cancelbots are a tool of the mythical Usenet cabal. Rationale Cancelbots must follow community consensus to be able to serve a useful purpose, and historically, technical criteria have been the only acceptable criteria for determining if messages are cancelable, and only a few active cancellers ever obtain the broad community support needed to be effective. Pseudosites are referenced in cancel headers by legitimate c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anti-spam
Various anti-spam techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) as opposed to not rejecting all spam email (false negatives) – and the associated costs in time, effort, and cost of wrongfully obstructing good mail. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials. End-user techniques There are a number of techniques that individuals can use to restrict the availability of their email addresses, with the goal of reducing their chance of receiving spam. Discretion Sharing an email address only among a limited group of correspondents is one way to limit the chance that the address will be "harveste ...
