A functional Magento 2 store can find itself in a situation where automatic spamming bots abuse its publicly available Magento 2 webforms. As an example of such a public webform, a Magento 2 custom contact form can be named. A popular way of protecting such web forms from abuse is by using CAPTCHA and similar tools when you create custom form in Magento 2.
Our extension provides support for reCaptcha as a protection against spam bots. This protection service is supported by default Magento 2. The spam protection option has been available since the Custom Form Builder version 1.0.9. Please update the extension if you are a current module user or control the version for a new installation.
