Stopping Spam Submissions from your Landing Page
Sometimes a bot will find your Landing Page and begin creating submissions. The data will not be true interested customers.
It is important that you stop these as soon as you notice them. They will generate fake customers in your system and you will want to delete them. If you are sending an Autoresponder to Landing Page submissions, you may also notice your Spam Complaints will increase and may cause you to lose email sending privileges. Review the Spam Policy here.
Follow these steps to stop the submissions.
Use a Hidden Field to Reduce Spam.
From the Actions Tab of the Landing Page you are using, choose the Use Hidden Field to Reduce Spam option by clicking the box and then Apply Changes.
