Comment validation for Django

This package provides chainable validation for django.contrib.comments. It's available under the MIT license.


  1. Download the source and unzip it or check it out with:

    hg clone http://bitbucket.org/fairview/fccv/

  2. Change directory to the top of the source tree and run python setup.py install or simply copy the fccv subdirectory to your PYTHONPATH.

  3. Add 'fccv' to your Django INSTALLED_APPS setting.

4) Run 'manage.py syncdb' to create the blacklist and banned IP tables, and load the starter set of blacklists.

5) By default, only local validation is performed. If you want to add Akismet or TypePad AntiSpam, you'll need to add another setting, FCCV_VALIDATORS, e.g.:

'fccv.check_comment_email', 'fccv.check_comment_ip', 'fccv.check_comment_link_limit', 'fccv.check_comment_name', 'fccv.check_comment_text', 'fccv.check_comment_url', 'fccv.check_typepad_antispam',


Then add your API key. For Akismet:

AKISMET_API_KEY = "your_API_key"

For TypePad:


6) If you want to write your own validator, create a module containing a function that takes two arguments: a django.contrib.comments.models.Comment and a django.http.HttpRequest. The function should either return None if it doesn't want to make a call on the comment, or a score from 0 to 1 indicating the probability that the comment is spam. Then just add that function to FCCV_VALIDATORS.

I learned how to apply the Tanimoto coefficient from the excellent O'Reilly book "Programming Collective Intelligence", by Toby Segaran. The book's a treasure trove.
