I wanted a global way to filter profanity w/out having to modify every model, view, or form. While middleware takes overhead, this technique is intended mainly for sites w/few postbacks. Hopefully this snippet will lead to more/better techniques in the comments below.

Usage (settings.py):

MIDDLEWARE_CLASSES = (
    'PROJECT_NAME.FILE_NAME.ProfanityFilterMiddleware',
)

from django.conf import settings
class ProfanityFilterMiddleware(object):
    def process_request(self, request):
        rpd = request.raw_post_data.lower()
        for w in settings.PROFANITIES_LIST:
            if rpd.find(w)!=-1:
                return HttpResponseRedirect("/static/html/rephrase.html")
