django-misery / README.md



A simple ban system for Django, that does nasty stuff to trolls wandering on your website.

Users banned the classical way are encouraged to bypass the ban by creating another users or changing of IP address. A nastier and probably more effective way to do is to use what is known as slowban, and errorban. This Django middleware implement those.


  • slowing page generation for miserable users
  • logging them out randomly
  • send a 404 from time to time...
  • ... or a 403...
  • ... or even a blank page if you want
  • last but not least, a wonderful ASP.NET error page made just for them

Hey, they deserved it!


  • lightweight, designed not to slow a single bit your website (from a non-miserable point of view, of course)
  • support both IPv4 and IPv6


  • does't currently support masks; yes, it can be handy against users having a botnet under control or in case of a user having a IPv6 range, but the current implementation favors speed over features

Installation & configuration

To install the app, you can use PIP: pip install django-misery; then add django_misery to your INSTALLED_APPS setting, and django_misery.middleware.miserize to you MIDDLEWARE_CLASSES.

The following settings can be personnalized:

  • MISERY_SLOW_STRENGHT: seconds that miserable users will have to wait at least (maximum twice longer) (default: 6)
  • MISERY_LOGOUT_PROBABILITY: percentage of probability a user will be disconnected (default: 10)
  • MISERY_403_PROBABILITY: same for 403 (default: 10)
  • MISERY_404_PROBABILITY: I'm gonna let you guess for this one (default: 10)
  • MISERY_WHITE_SCREEN_PROBABILITY: same for a nice, 100% pure white (not a single subpixel in the viewport will be off, I promise) (default: 20)
  • MISERY_ASP_ERROR_PROBABILITY: a free bonus for the ASP lovers (and I'm sure they are plenty around here), the template renders just great. Oh and: to make it even more beautiful, it's in French (default: 20). Have a quick look:

ASP error overview

By default, the miserable users have therefore approximately a 50-50 chance to see the real page. They won't stay long, I promise.
