This is a simple {spamtrap}[http://en.wikipedia.org/wiki/Spamtrap] to fight {spamdexing}[http://en.wikipedia.org/wiki/Spamdexing]. You can create bogus form fields ({honeypots}[http://en.wikipedia.org/wiki/Honeypot_%28computing%29]) that will be filled-in by spambots. When these forms are submitted, the content will be discarded while still returning a 200 response.
=== Installation
In Rails 2.3, add the following to your environment.rb:
config.gem 'spamtrap'
In Rails 3+ (or if using Bundler), add the following to your Gemfile:
gem 'spamtrap'
=== Example
Declare the controller actions you want the spamtrap enabled for:
class CommentsController < ApplicationController
spamtrap :sarah_palin_walks_with_dinosaurs, only: %i(create update)
endIn your views, add a call to the "spamtrap" form builder to your forms to output the honeypot fields:
- form_for @comment do |f|
= f.spamtrap :sarah_palin_walks_with_dinosaurs, class: 'reindeer_jerky'
%fieldset
= f.label :body
= f.text_area :body
= f.submitNow you just need to hide the spamtrap from your real users by adding this to your CSS:
.reindeer_jerky { display: none; }
The spamtrap mix-in can also take an optional block, where you can do more advance things -- like swapping the honeypot with a real form parameter.
=== To Do
- Add a cryptographic nonce to prevent replay attacks. It would probably be an MD5 hash consisting of a timestamp, ip address and a secret token. The timeout would be configurable.
- Consider field name mutation throughout form.
- Write some tests. Ack!=== License
