This is the "unobtrusive comments moderation" code from http://www.djangosnippets.org/snippets/112/ , but updated so it works properly with Django 1.0.

There are only a few small changes reflecting changes in the comments, contenttypes, and signals APIs.

For full background, see the original snippet: http://www.djangosnippets.org/snippets/112/

    """
    Applies comment moderation to newly-posted comments.
    
    Moderation happens in two phases:
    
        1. If the object the comment is being posted on has a method
           named ``comments_open``, it will be called; if the return
           value evaluates to ``False``, the comment's ``is_public``
           field will be set to ``False`` and no further processing
           will be done.
    
        2. If the object did not have a ``comments_open`` method, or
           if that method's return value evaluated to ``True``, then
           the comment will be submitted to Akismet for a spam check,
           and if Akismet thinks the comment is spam, then its
           ``is_public`` field will be set to ``False``.
