Invisible CAPTCHA to avoid SPAM submissions

Finally found a nice SPAM protection solution
http://www.ngenworks.com/blog/invisible-captcha-to-prevent-form-spam/

Example HTML markup:

<label for="email">Email:</label>
<input name="email" type="text" value="" />
<span class="confirmation-field">
<label for="email-confirmation">Email confirmation:</label>
<input name="email-confirmation" type="text" value="" />
</span>

CSS:

.confirmation-field { display: none; }
