is_bot is a clean rewrite of less_reverse_captcha
It is a simple way to make your forms bot-proof. The effectiveness of the solution is open to discussion. I have used it on a low traffic site and it seems to have reduced the bot-attack considerably.
It is very simple to use. Just install it in your rails app and perform the following steps.
In your model class:
class User < ActiveRecord::Base validate_captcha end
In your model's view:
form_for @user do |f| captcha_reverse_field :user end
And that's it.
Please report the issues through gitHub's issues.
