Pseudo Captcha

The field cliving_mandatory is for spam protection (remove it if you don't need spam protection). Ask a calculation task there. It's good to write the task down in words, so most manual spammers are not able to understand. The first letter c in the name cliving_mandatory represents the required calculation result. In our example it is 99 because the ASCII code of the lower case letter c is 99. So aliving_mandatory would need the result 97, bliving_mandatory 98 and so on.

However...

The pseudo captcha shown above helps in many cases, but if a form is maliciously spammed using automation, it can easily be bypassed. A stronger protection is offered by Google reCAPTCHA.
