 * Love the simplicity of this form…
 * The “captcha” number generated is not different each time. Is that correct?

 * Hi,
 * Yes and no, please check the FAQ:
 * _The captcha is a random number that changes every day.
    In older plugin versions
   it changed every session. But the capcha has been simplyfied, because it’s not
   using a PHP session anymore.

 * Hello Guido,
 * i really like your plugin, however the CAPTCHA is really easy to defeat, if someone
   wants to spam your forum. Wouldnt it be smarter to include a real CAPTCHA solution
   that can be configured via the wordpress options? E.g. an option for a reCAPTCHA
   API key, that can be set via WP-CLI?
 * This would really boost your plugin a lot regarding secure use!
 * Best regards!

 * Hi,
 * I really dislike the reCaptacha, but I agree with you that mine isn’t very solid.
 * I strongly prefer a build in captcha feature. How about a captcha sum, as for
   example described [here](http://html-tuts.com/simple-php-captcha/)?

 * Hello Guido,
 * i understand your concerns regarding reCAPTCHA and probably the dependency of
   google. However, CAPTCHA solutions are extremely difficult to design and a lot
   of projects already died due to their weaknesses and their inefficiency. The 
   solution you suggested is barely more secure than the one you are using right
   now, as an attacker might circumvent it easily.
    Some hints are given on this
   page: [https://www.gravityforms.com/rip-captcha/](https://www.gravityforms.com/rip-captcha/)
   Maybe a honeypot solution is OK for now, even though it is not very secure either,
   but at least it doesnt disturb the users. Unfortunately, Googles noCAPTCHA is
   the most advanced CAPTCHA until now. MAybe also an integration of Akismet Spam
   Plugin could work. However, i havent checked that in detail

 * Hi,
 * My form already has a honeypot field 🙂 And until now I did not get a single 
   complaint from a user regarding SPAM via my forms. And my plugin has been around
   several years now. This means I can be lucky, or it’s because of the honeypot,
   or bots like the more popular forms more. Older plugin versions had a session-
   based Captcha (not very strong either), but it was using a PHP session and this
   caused problems on a few sites. So I’ve removed it. Personally I think a simple
   numeric Captcha (for humans) with a honeypot (for bots) isn’t that bad. But not
   the best, I agree. Will look into reCaptcha, maybe it’s not very difficult to
   include this, as extra feature.
