Trac Spam Filtering

A plugin is being developed that will allow different ways to reject contributions that contain spam. This plugin requires the forthcoming Trac release 0.10. It currently needs at least [3180], which has the necessary hooks for spam filtering to work.

Current state: highly experimental and mostly untested :-P

Suported Filtering Stragies

Regular Expressions

The regex filter reads a list of regular expressions from a wiki page named “BadContent”, each regular expression being on a separate line inside the first code block on the page, using the ​Python syntax for regular expressions.

If any of those regular expressions matches the submitted content, the submission will be rejected.

IP Blacklisting

The ip_blacklist filter uses the third-party Python library ​dnspython to make DNS requests to a configurable list of IP blacklist servers.

Akismet

The akismet filter uses the ​Akismet web service to check content for possible spam. The use of this filter requires a ​Wordpress API key.
