Wikipedia:Spam

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.

Some articles, especially those pertaining to Internet topics, are prone to aggressive spamming from multiple websites.

If articles have spam, and you haven't the time or ability to remove it, you can tag them with {{}}. This template expands to the following:

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

A fourth template, used for citation spam, is {{}}, which looks like this:

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.

Citation spamming is the illegitimate or improper use of citations, footnotes or references. Citation spamming is a form of search engine optimization or promotion that typically involves the repeated insertion of a particular citation or reference in multiple articles by a single contributor. Often these are added not to verify article content but rather to populate numerous articles with a particular citation. Variations of citation spamming include the removal of multiple valid sources and statements in an article in favor of a single, typically questionable or low-value, web source. Citation spamming is a subtle form of spam and should not be confused with legitimate good-faith additions intended to verify article content and help build the encyclopedia.

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:

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.
