Extension:AbuseFilter

The AbuseFilter extension allows privileged users to set specific actions to be taken when actions by users, such as edits, match certain criteria.

For example, a filter could be created to prevent anonymous users from adding external links, or to block a user who removes more than 2000 characters.

Requirements
There are no required dependencies for this extension, but it is recommended you install ext-AntiSpoof>Special:MyLanguage/Extension:AntiSpoof|Extension:AntiSpoof to use string normalization features.

User rights
Once you installed the extension, you'll have to set up the user rights in  .

For example, the following sample configuration would allow sysops to do everything they want with AbuseFilter, and everyone to view the log and see public filter settings:

Filters marked as private can only be viewed by users with either the abusefilter-modify or abusefilter-view-private permission.

Creating and managing filters
Once the extension has been installed, filters can be created/tested/changed/deleted and the logs can be accessed from the Abuse filter management page Special:AbuseFilter.

 * To import filters from Wikipedia: When you have installed the extension, go to w:Special:AbuseFilter, choose a filter (say w:Special:AbuseFilter/3), then click "Export this filter to another wiki", copy the text, go to "Special:AbuseFilter/import" on your wiki, paste the text.

API
AbuseFilter adds two API list modules, one for details of abuse filters ("abusefilters") and one for the abuse log, since it is separate from other MediaWiki logs ("abuselog"). It is not possible to create or modify abuse filters using the API.

list = abusefilters
List information about filters


 * Parameters
 * : The filter id to start enumerating from
 * : The filter id to stop enumerating at
 * : The direction in which to enumerate (older, newer)
 * : Show only filters which meet these criteria (enabled|!enabled|deleted|!deleted|private|!private)
 * : The maximum number of filters to list
 * : Which properties to get (id|description|pattern|actions|hits|comments|lasteditor|lastedittime|status|private)

When filters are private, some of the properties specified with  will be missing unless you have the appropriate user rights.


 * Examples

 * Example

Possible errors

 * Some users might experience that creating new filters or modifying old filters fail and the user just gets redirected to the original page. If the Wiki is using SSL certificates, this error could possibly be because of the value, which might be using "http://" instead of "https://". An indication of this error will be, the browser giving https warning for Special:AbuseFilter pages. (Topic:T23dyyih0ofjada5)
