Captcha - new feature

[Matho]

Have you thought about implementing some captcha system to refinerycms-inquiries? Raptcha https://github.com/ahoward/raptcha, seems to be efficient and easy to integrate captcha system.

I've thought about it but I seriously dislike CAPTCHA.

If you wanted to add one then a configuration option would be welcome to have it disabled by default. I believe that CAPTCHA can lead to poor usability for the user though I do know some sites require it.

I also dislike captcha systems like reCaptcha - it is hard to read. But when I set email notification on without captcha, all spam inquiries will resend to my mail. If somebody points service like Acunetic web vulnerability scanner to that site, he can spam that site without typical spam words.

Raptcha is simple, but it doesn't have sound feature for blind people.

I think we need to comply with the US accessibility guidelines by
default. Does Raptcha comply?

According to this article http://www.evengrounds.com/developers/does-wcag-2.0-allow-captcha no.

"When WCAG requires to provide a text alternative for non-text content, it also makes a couple of exceptions. One of them is CAPTCHA. As a text alternative for an image CAPTCHA would defeat it's purpose, WCAG requires to provide alternatives for different sensory perception."

reCaptcha should comply, because there is also sound perception.
