No, the form will not submit unless the captcha value is entered properly. We have a few clients that are getting hit pretty hard with spam submissions. We have an additional few that have captcha in place and are not getting the spam submissions. With that being said, we are putting captcha in place on the ones that are having the problem, however, this one is still getting approx. 4-8 spam submissions a day. Prior to captcha being added, they were getting a dozen or more a day so I can certainly see the difference, however, it is still happening.
