Once you’ve followed some of the steps to control spam you will need to review your comments and approve those you want to be displayed on your blog.
You can see all comments on your WordPress website by clicking on the comments menu in WordPress.
On the comments page, you will see four different tabs. Comments that need your approval will appear under the Pending tab.
To approve a comment take your mouse over to the comment, and you will see actionable links appear below the comment. Click on Approve to make a comment publicly visible on your website. You can also reply to a comment by clicking on the reply link. Replying to a comment automatically approves the comment as well.
If you have e-mail notification set up for comments, you may moderate individual comments via e-mail. The e-mail will include links to approve the comment, mark it as spam, or delete it.
