extraterrestrialicious web apps

Quite a few years ago I wrote a plugin for Ruby on Rails. It checks incoming client connections against DNS Blackhole Lists. It has worked quite well over the years. In the mean time I moved all my code from Subversion to Git, but somehow never moved the plugin. Until now!

If your Rails application is plagued by spam and/or you would like to add a layer of zombie-protection, you might want to check it out. It’s clean and simple and does what is promises on the box:

This plugin checks if a user of your web application is listed in DNSBLs

(DNS Blackhole Lists). These are lists of misbehaving IP addresses.
