Wikipedia:SPAM 

This page documents an English Wikipedia content guideline. It is a generally accepted standard that editors should attempt to follow, though it is best treated with common sense and the occasional exception. Any substantive edit to this page should reflect consensus. When in doubt, discuss first on the talk page.

There are two types of wikispam. These are advertisements masquerading as articles and external link spamming.

Advertisements masquerading as articles

See also: Wikipedia:NOTADVERTISING#ADVERTISING.

Articles considered advertisements include those that are solicitations for a business, product or service, or are public relations pieces designed to promote a company or individual. Wikispam articles are usually noted for sales-oriented language and external links to a commercial website. However, a differentiation should be made between spam articles and legitimate articles about commercial entities.

Blatant examples of advertising masquerading as articles can be speedily deleted by tagging the articles with {{db-spam}}. Other advertisements posted on Wikipedia can be dealt with by either proposed deletion or listing them on Wikipedia:Articles for deletion. On some occasions, the content can be removed temporarily on the basis of a suspected copyright violation, since the text is often copied from another website and posted anonymously.

When an article on an otherwise encyclopedic topic has the tone of an advertisement, the article can often be salvaged by rewriting it in a neutral point of view. Elements of articles about products or services with brand names can also be combined under a common topic or category to facilitate unbiased and collaborative information by including information about the competition and about different alternatives.

Tagging articles prone to spam

Some articles, especially those pertaining to Internet topics, are prone to aggressive spamming from multiple websites. Please tag them with {{Cleanup-spam}} to advise the Wikipedia community to watch the article for abuse. This template expands to the following:

 This article or section may contain spam.
Wikipedia spam consists of external links mainly intended to promote a website. Wikipedia spam also consists of external links to websites which primarily exist to sell goods or services, use objectionable amounts of advertising, or require payment to view the relevant content. If you are familiar with the content of the external links, please help by removing promotional links in accordance with Wikipedia:External links. (You can help!)

It's a good idea to remove this tag once the attacks die down.

Another possible tag to use is {{advert}}, which expands to the following:

 This article or section is written like an advertisement.
Please help rewrite this article from a neutral point of view.
For blatant advertising that would require a fundamental rewrite to become encyclopedic, use {{db-spam}} to mark for speedy deletion.

The third useful template is a substituted template {{subst:NoMoreLinks}}, visible only while the page is being edited. After spam links have been removed from a Wikipedia article, this template can be substituted into the top of the external links section of the frequently spammed article as a preemptive measure.

<!--==========================({{NoMoreLinks}})============================
    | PLEASE BE CAUTIOUS IN ADDING MORE LINKS TO THIS ARTICLE. WIKIPEDIA  |

    |           Excessive or inappropriate links WILL BE DELETED.         |

External link spamming

Shortcuts:
WP:LINKSPAM
WP:SPAM#LINK
Main articles: Links normally to be avoided and Wikipedia:Conflict of interest

Adding external links to an article or user page for the purpose of promoting a website or a product is not allowed, and is considered to be spam. Although the specific links may be allowed under some circumstances, repeatedly adding links will in most cases result in all of them being removed.

Adding links to online free videos that promote a site or product is not allowed [see exception below]. Often these videos have been uploaded in violation of their copyright which adds an additional reason for not linking to them. A video is a spamming video if:

Exception: Generally, a video is not a spamming video if it refers to the official site associated with the Wikipedia article. For example, if the Wikipedia article is on a movie named "xyzMovie" and the official site for the movie is "xyzMovie.com" then links or references to "xyzMovie.com" are legitimate for a video at a video sharing page—however, all other links at that video page still must also be legitimate. Some judgement is needed here. If the posted video just advertises a bunch of products associated with the movie, then it is a spamming video even though it refers to the official site.

It is also important to avoid giving an opportunity to spammers. Sometimes, the way an article is phrased attracts spammers. For example,

because it is far easier to add a link to the end of this sentence than to add encyclopedic content.

Source soliciting

Source solicitations are messages on article talk pages which explicitly solicit editors to use a specific external source to expand an article. The current consensus on Wikipedia is that templates, categories and other forms of anonymous solicitation are inappropriate. Every article on Wikipedia can be expanded as a matter of course, but the question is in the details on a per-article basis. It is not possible to simply say "all articles of X type can be expanded using Y source".

There is no hard rule on when this crosses over from being a legitimate attempt to improve the article into being internal spam, but some guidelines and questions to consider:

External link spamming with bots

A few parties now appear to have a spambot capable of spamming wikis from several different wiki engines, analogous to the submitter scripts for guestbooks and blogs. They have a database of a few hundred wikis. Typically they insert external links. Like blog spam, their aim is to improve their search engine rankings, not to directly advertise their product.

If you see a bot inserting external links, please consider checking the other language wikis to see if the attack is widespread. If it is, please contact a sysop on the Meta-Wiki; they can put in a Wikimedia-wide text filter. Any Meta sysop can edit the Wikimedia-wide spam blacklist to add or remove the patterns that are recognized by the filter, with the changes taking effect immediately. New links can also be added to the list if a new spammer should start making the rounds.

Sysops are authorised to block unauthorised bots on sight. Spam bots should be treated equivalently as vandalbots. Edits by spambots constitute unauthorised defacement of websites, which is against the law in many countries, and may result in complaints to ISPs and (ultimately) prosecution.

The link spam problem extends far beyond Wikimedia projects, and is generally worse on smaller wikis where the community struggles to keep it clean. meta:Wiki Spam page (now obsolete) has some more general information and advice for users of wikis elsewhere on the internet, while the MediaWiki Anti-Spam Features page describes features available in MediaWiki (for administrators running this software)

Inclusion of one spam link is not a reason to include another

Many times users can be confused by the removal of spam links because other links that could be construed as spam have been added to the article and not yet removed. The inclusion of a spam link should not be construed as an endorsement of the spam link, nor should it be taken as a reason or excuse to include another.

Affiliate Links

Even if they are related to the subject or is an official page for the subject, external links containing affiliate or referral codes can be considered spam.

How not to be a spammer

Shortcut:
WP:SPAMMER

Sometimes, people come to Wikipedia with the intention of spamming—creating articles which are mere advertisements or self-promotion, or spewing external links to a Web site over many articles.

Some people spam Wikipedia without meaning to. That is, they do things which Wikipedians consider to be spamming, without realizing that their actions are not in line with building an encyclopedia. A new editor who owns a business may see that there are articles about other businesses on Wikipedia, and conclude that it would be appropriate to create his own such article. A Web site operator may see many places in Wikipedia where his or her site would be relevant, and quickly add several dozen links to it.

The following guidelines are intended to suggest how not to be a spammer—that is, how to mention a Web site, product, business, or other resource without appearing to the Wikipedia community that you are trying to abuse Wikipedia for self-promotion.

  1. Review your intentions. Wikipedia is not a space for personal promotion or the promotion of products, services, Web sites, fandoms, ideologies, or other memes. If you're here to tell readers how great something is, or to get exposure for an idea or product that nobody's heard of yet, you're in the wrong place. Likewise, if you're here to make sure that the famous Wikipedia cites you as the authority on something (and possibly pull up your sagging PageRank) you'll probably be disappointed, because Wikipedia uses nofollow on all external links, thereby causing search engines to effectively ignore them.
  2. Contribute cited text, not bare links. Wikipedia is an encyclopedia, not a link farm. If you have a source to contribute, first contribute some facts that you learned from that source, then cite the source. Don't simply direct readers to another site for the useful facts; add useful facts to the article, then cite the site where you found them. You're here to improve Wikipedia—not just to funnel readers off Wikipedia and onto some other site, right? (If not, see #1 above.)
  3. The References section is for references. A reference directs the reader to a work that the writer(s) referred to while writing the article. The References section of a Wikipedia article isn't just a list of related works; it is specifically the list of works used as sources. Therefore, it can never be correct to add a link or reference to References sections if nobody editing the text of the article has actually referred to it.
  4. Don't make a new article for your own product or Web site. Most often, when a person creates a new article describing his or her own work, it's because the work is not yet well-known enough to have attracted anyone else's attention, much less independent and reliable sources against which the content can be verified. Articles of this sort are usually deleted. Wikipedia does indeed have articles about popular products and Web sites, but it is not acceptable to use Wikipedia to popularize them.
  5. Don't gratuitously set off our spam radar. There are certain stylistic behaviors that will say "spam!" loud and clear to anyone who's watching:
  6. If your product is truly relevant to an article, others will agree—try the talk page. We usually recommend that editors be bold in adding directly to articles. But if the above advice makes you concerned that others will regard your contribution as spam, you can find out without taking that risk: Describe your work on the article's talk page, asking other editors if it is relevant.
  7. Do not add an external link to your signature. However, external links to Wikimedia projects are exempt from this rule. For example, Wikimedia Meta-Wiki. (Although Interwiki links are preferable to external links for that purpose.)

Warning spammers

{{subst:uw-spam1}} is a useful "first warning" to put on the Talk page of a spammer. For new users, an alternative is {{subst:welcomespam}} may be used for users who may have added spam or inappropriate external links in good faith.

Subsequent offenses can be tagged with {{subst:uw-spam2}}, then {{subst:uw-spam3}} (warning of possible block) and {{subst:uw-spam4}} (final warning). If an editor spams numerous articles in a systematic fashion, they may be warned with {{subst:uw-spam4im}} as the only warning that they will receive before they are blocked. The template {{subst:uw-sblock}} indicates that the spammer has been blocked.

If you have tagged an article for speedy deletion with {{subst:db-spam}} because it is blatant spam, you may add {{subst:spam-warn}} to the originating editor's talk page to warn them of the impending deletion, and to allow them to possibly edit the article so it is no longer spam.

Please remember to substitute these templates using for example {{subst:uw-spam1}} instead of {{uw-spam}}.

Dealing with spam

Sometimes an article attracts so many improper external links that it "crosses the spam event horizon". Removing all the links and using the {{dmoz}} template to place a single external link to the appropriate DMOZ category can provide much needed relief.
