Meerkat's security settings exist to help protect the reputation of your website. For example, you can decided to automatically check all submitted comments for spam; if desired, have them automatically removed before they ever reach the Control Panel or your site.
Labeled "1" in the image above.
When this option is enabled, new comments will automatically be checked for spam. If you are automatically publishing comments from authenticated users, those comments will not be checked (comments from anonymous site visitors will be checked, however).
Labeled "2" in the image above.
When this option is enabled, comments flagged as spam will automatically be removed. Enabling this option will not give you the opportunity to review for comments that may have been incorrectly marked as spam!
Labeled "3" in the image above.
Enable this setting to automatically submit span/ham results to any configured third-party spam service. This will help to improve the spam detection methods used by these services, but will send some site data to these services. Each service is governed by it's own terms and conditions, so be sure to check those if you want to enable this setting.
These settings are labeled "4" and "5" in the image above.
Akismet is an advanced, hosted, anti-spam service that can be used to check your incoming comments for spam. Usually seen within WordPress configurations, Meerkat provides seamless integration for your Statamic site.
To enable Akismet on your Statamic site, visit https://akismet.com/ and setup your account. You will receive an API key once your site has been setup. Enter your API key and the Front Page (usually your root domain name,
https://stillat.com for this site) within the Security settings section; that is all you have to do.
