Akismet Spam Checking for django.contrib.comments

So I was trying to get Akismet working on our comments system the other day. I ran across Brant Steen's Post for a way to use Django signals to handle it. Sadly, this was out of sync with the Akismet python library. So, I updated it and here's the end result:

from django.contrib.comments.models import Comment
from django.contrib.comments.signals import comment_will_be_posted
from akismet import Akismet, AkismetError
from django.conf import settings

def spam_check(sender, comment, request, **kwargs):
    api = Akismet(agent="Python Request/1.0")
    api.setAPIKey(settings.AKISMET_KEY, 'http://example.com')

        real_key = api.verify_key()
        if real_key:
            is_spam = api.comment_check(
                    'user_ip': request.META.get('HTTP_X_FORWARDED_FOR') or request.META['REMOTE_ADDR'], 
                    'permalink': comment.get_absolute_url(),
                    'user_agent': request.META.get('HTTP_USER_AGENT'),
            if is_spam:
                return False
                return True
            print 'Warning: key is invalid?'
    except AkismetError, e:
        logger.warning('Error:Something went wrong, allowing comment. %s:%s' % (e.response, e.statuscode))
        return True


I added the import statement for the above signals.py to my project-app folder's ___init___.py file to make sure it was imported and connected properly. So far, so good. Though you may want to setup a 400 error page, if you want to be nice to any false-positives.
