Using CAPTCHA forms (or keyword validation), like the VVC contribution can prove to be difficult for those customers that don't pay close attention to instructions!
What this Does: Filters all the terms that are commonly found in spam emails and stops the form submission until the spammy terms are removed and set minimum and maximum lengths for the enquiry field; also removes any irregular characters and refreshes the form with the illegal characters removed (if the remaining characters are below the minimum limit).
You can also set minimum and maximum lengths for the enquiry field.
