WordPress allows site administrators to moderate comments by entering words or URLs in the Comment Moderation field that should not be included in comments. Any comments containing those words or URLs will be held for moderation by the admin before being published. The admin can then approve or reject the comment.

1. WordPress - Moderate Comments

2. Step (1) − Click on Settings → Discussion in WordPress.

3. Step (2) − The Discussion Setting page gets displayed.

5. In the Comment Moderation field, enter those words or URLs you do not want any visitor to add
comments. Whenever a visitor gives any comments it would be moderated by the admin first and
then published.
Step (3) − Click on Save Changes.
