LocalSettings.php
To prevent a spammer from saving wiki edits with problematic content, use the variable '$wgSpamRegex'. Set the variable in LocalSettings.php (overriding the value appearing in DefaultSettings.php). Set it to a regular expression (RegEx) for matching on any URLs (or parts of URLS) which you do not want to allow users to link to. You can also match any other bad content which you wish to ban. Users are presented with an explanatory message, indicating which part of their edit text is not allowed.
RegEx Examples
- Sample Regular Expressions to block common spam fragments
$wgSpamRegex = "/overflow:\s*auto;\s*height:\s*\dpx/"; #big net $wgSpamRegex = "/height:\s*\dpx/"; #bigger net
Regular Expressions Howto
The SpammerBlockPattern is formatted using Regular Expression (RegEx) syntax.

Spam Blacklist Extension
The above approach may become too cumbersome. Another approach is to have a long blacklist identifying many known spamming URLs and spam terms, in a more readable format (not a single regular expression). With the Spam Blacklist extension you can allow some of your users to edit the blacklist on a wiki page, and you can fetch updates from external sources.

- Bad Behavior (http://www.ioerror.us/software/bad-behavior/) is a set of PHP scripts which prevents spambots from accessing your site by analyzing their actual HTTP requests and comparing them to profiles from known spambots. It goes far beyond User-Agent and Referer, however. Bad Behavior is available for several PHP-based software packages, and also can be integrated in seconds into any PHP script.
