Change comment approval settings in WordPress
To ensure that only authorized comments appear on your WordPress site, follow these steps to enable options for comment approval.
- Sign in to WordPress.
 - On the left-side menu, select Settings and then Discussion.
 - In the Before a comment appears section, select the checkbox next to each of the following options to enable them:
        
- Comment must be manually approved.
 - Comment author must have a previously approved comment.
 
 - (Optional) If you want to be notified whenever you need to approve or delete the comment, in the Email me whenever section, select the box next to A comment is held for moderation.
 - Scroll to the bottom of the page and select Save Changes.
 
When enabled, these options will prevent spammers from leaving unauthorized comments on your site.
