If you're sick of banning or deleting troublemakers on your Drupal website, you might want to check out Misery, the module designed to give trolls a taste of their own medicine . Creating a random length delay for a user, redirecting them to a random page, presenting them with a 404 error, and crashing their browser if they're using IE6 are just a few of the things you can make users endure with Misery. I'm still waiting patiently for a Punch In the Nose module, but this is a good start.
