Thespam blacklist is a control mechanism that prevents an external link from being added to any page when the URL matchesregex rules listed atthe local orglobal blacklist, or belongs to a site listed atSpecial:BlockedExternalDomains. These lists mostly containspam sites, but also includeURL redirection services (which could otherwise be used to bypass blacklisting),[1] some sites which are persistently abused for shock effects, and some sites which have been added after independent consensus.[2]
Specific links can be allowed by overruling the blacklisted links through addition toMediaWiki:Spam-whitelist.
The spam blacklist is supported by MediaWiki'sSpamBlacklist andAbuseFilter extensions.

MediaWiki:Spam-blacklist is a localized version ofm:Spam blacklist, a similar blacklist that affects allWikimedia Foundation projects. Additions to the local spam blacklist will only affect the English-language edition of Wikipedia, not other projects. Blacklisting requests may be made atMediaWiki talk:Spam-blacklist. However, blacklisting a URL should be used as a last resort against spammers. You should consider the following before requesting that a URL be blacklisted:
Note that the blacklist only affects live links. Most non-clickable URLs (such as those contained within anowiki tag) are not affected. However, URLs inedit summaries are affected.
Compelling evidence of a problem should be given when requesting a page to be listed (preferably by givingdiffs).
example.com accidentally is affecting links togood-example.com).This is not the section to request links to be removed!When requesting that a URL be delisted, you should give compelling evidence as to why it should be delisted. Cases of this could include (but are not limited to) hijacked domains being returned to their rightful owner or a site with content that violates copyrights cleaning up their act.
