[edit] Overview

This page relates to fighting spam postings, otherwise known as wikispam, in MediaWiki.

[edit] Notes

It looks like there are basically two methods for preventing spam. Both of them match submitted edits against a regex string, and reject those which fail the test. One method is built in and allows only a single regex string; the other requires an extension ("ambiguously licensed") and allows blacklist data to be pulled from remote sites.

A tip for small sites: always monitor your site's RSS feed to see what changes are being made by others. A lot of spam does not show up when looking at the page as displayed in a browser; the content is hidden using CSS so that it will get picked up by search 'bots but not noticed by editors.

[edit] Links

  • MediaWiki documentation
    • Wiki Spam: a detailed explanation of the problem
    • Anti-spam Features: simple built-in regex blacklist
    • SpamBlacklist extension: more powerful than the built-in regex blacklist. The README file explains most of it, but doesn't make it clear that there are two files you need to install: SpamBlacklist.php and SpamBlacklist_body.php
