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".


  • Download and place the file(s) in a directory called SmiteSpam in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'SmiteSpam' );
  • Run the update script which will automatically create the necessary database tables that this extension needs.
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


User rightEdit

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.
