Antispam

The antispam gem helps prevent spam in your Rails applications by providing tools that check spam against powerful spam-prevention databases, accessible for free.

The first feature checks against an IP database of spam, allowing you to stop spammers who are prolific and have been detected on other websites. It relies on the lightning-quick httpbl from Project Honey Pot.

Mounting it

# Gemfile
gem "antispam"

# config/routes.rb
mount Antispam::Engine, at: "/antispam"
