The SmiteSpam extension provides a special page "Special:SmiteSpam" helping administrators identify and delete spam pages.



Navigate to "Special:SmiteSpam" in order to run the analyzer and get a list of pages that the extension identifies as spam. You can use the interface to block users, delete pages created by them or trust a user you know to be good contributors.

The list of trusted users can be viewed and edited at "Special:SmiteSpamTrustedUsers".



You can download the SmiteSpam code, in .zip format, here:


You can also download the code directly via Git from the MediaWiki source code repository (see available tags). From a command line, you can call the following:

git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/SmiteSpam

To view the code online, including version history for each file, go here.



To install the extension, place the entire 'SmiteSpam' directory within your MediaWiki 'extensions' directory, then add the following line to your 'LocalSettings.php' file:

wfLoadExtension( 'SmiteSpam' );

Once you have the code set up, SmiteSpam has a database table, "smitespam_trusted_user", that must be created. You will need to create it by going to MediaWiki's /maintenance directory and calling the following:

php update.php



User right


By default, this extension can only be used by sysops. You can change it: e.g. let also bureaucrats use it by adding the following line to your "LocalSettings.php" file.

$wgGroupPermissions['bureaucrat']['smitespam'] = true;


Parameter Default Value Comment
$wgSmiteSpamThreshold 0.7 Pages analyzed as having a spam "probability" higher than this will be shown on special page.
$wgSmiteSpamIgnoreSmallPages true Should SmiteSpam ignore pages smaller than 500 characters?
$wgSmiteSpamIgnorePagesWithNoExternalLinks true Should SmiteSpam ignore all pages that don't have any external links outside of template calls?
$wgSmiteSpamQueryPageSize 500 Number of pages to analyze in one AJAX request. (Setting this too high can cause timeouts.)
$wgSmiteSpamDisplayPageSize 250 Number of pages to display in one paginated page.

$wgSmiteSpamCheckers is a parameter that lets you choose which "checkers" you want to run and how much weight (value) you want to give to each of their reports.

By default, this is set to:

$wgSmiteSpamCheckers = [
	'ExternalLinks' => 1,
	'RepeatedExternalLinks' => 1,
	'Wikitext' => 1,



Checks how much of the text (ratio) is external links.


Checks whether there are repeated external links.


Checks how much wikitext is there in the contents of the page.
