Hi,
the recaptcha plugin you provided seems to have a very low securised implementation. (https://github.com/KriesiMedia/enfold-library/tree/master/integration%20plugins/Enfold/Enfold%20G%20Recaptcha)
Spam bots can easily reactivate the disabled/hidden submit button without properly validating the recaptcha process.
Several clients reported us this issue with unwanted porn spams and scams in their emails. Can you dig into this for a quick update?
Thank you.
