When using the Akismet Anti-Spam plugin with Gravity Forms, a Spam label will be available on the entry that allows you to easily mark it as spam. Multiple entries may also be marked as spam in bulk using the “Spam” option available in the Bulk Actions drop down on the Entry List page. To have entries automatically marked as spam as soon as they are submitted, simply go to the Forms->Settings page and mark the “Akismet Integration” option as “Yes”. If the Akismet plugin is not active, you will not see this option, or the Spam label option on the entry.
