reCaptcha plugin for Blosxom

After looking for some appropiate way to deal with comment spam I found reCaptcha. They provide a nice form presenting a capture image. Their service is provided for free, all you need is to register. They even have an API that has all you need. It gets even better: there's already a Perl module for using this API. Having almost all pieces in place I decided to write a little Blosom plugin for using reCaptcha. The plugin was tested with the writeback module, though I'm sure it works with others as well.

All you need to do is to

  • drop the plugin in your plugin directory, make it executable.
  • add your recaptcha keys to the module, add the form to your writeback module by placing $recaptcha::form and $recaptcha::msg in your writeback form
  • check the recaptcha result in the writeback module using recaptcha::validate()

Details can be found in the module's perldoc. You can download the module here. Leave a comment if you have any questions...
