Trac reCAPTCHA filter

Introduction

This filter uses the free service from http://recaptcha.net to check if a content submitter is a human or a computer. Once a captcha is solved it will allow a configurable number of submissions for a configurable time period until it requires another captcha to be solved.

Release 1.5 also includes mailhide functionality which hides most email addresses behind a captcha, if the email address is already a link for something else we show only the full name, or local part of the email address.

This implementation was tested with Trac 0.10.

Installation

• download the attached .egg file, copy it to $tracdir/plugins and restart trac.
• optionally install the TracWebAdmin plugin.
