So I ended up implementing reCaptcha Non-JavaScript API as suggested by Javier.

Added the following in my view:

<p class="text-black-11px-17px" style="color: red;"><%=flash[:captcha_error]%></p> 
<script type="text/javascript" 
src="http://www.google.com/recaptcha/api/challenge?k=PUBLIC_KEY_HERE"></script>
<noscript>
   <iframe
src="http://www.google.com/recaptcha/api/noscript?k=PUBLIC_KEY_HERE"
       height="300" width="500" frameborder="0"></iframe><br>
   <textarea name="recaptcha_challenge_field" rows="3" cols="40">
   </textarea>
   <input type="hidden" name="recaptcha_response_field"
       value="manual_challenge">
</noscript>

Added the following in my controller:

# verify reCaptcha
uri = URI.parse("http://www.google.com/recaptcha/api/verify")
response = Net::HTTP.post_form(uri, {
  "privatekey" => "PRIVATE_KEY_HERE", 
  "remoteip" => request.env['REMOTE_ADDR'], 
  "challenge" => params[:recaptcha_challenge_field], 
  "response" => params[:recaptcha_response_field]
})

flash[:captcha_error] = nil
if ((@contact.valid?) && (response.body.include? "success")) 
    # VALIDATION SUCCESSFUL - SEND THE EMAIL
elsif (response.body.include? "false")
   flash[:captcha_error] = "The CAPTCHA you entered is invalid. Please try again."
   render :action => 'contact'        
else
    render :action => 'contact'
end

There is no need to use a plugin, is recommendable to use when they are available, but is not a mandatory thing. Probably the "Do-it yourself" installation needs more steps but definitely will works. Take a look for example at the reCAPTCHA documentation, there is a complete section dedicated to explain the use of the library without plugins.

Basically there are two approaches:

  1. The Standard Challenge and Non-JavaScript API.
  2. The reCAPTCHA AJAX API

With any of those ways, depends of your needs, hopefully you should have captcha working in a lot of scenarios without troubles. The API is well explained and have a few examples.

Hope this helps.
