WordPress - Moderate Comments
In this chapter, we will learn to Moderate Comments in WordPress. Comment moderation is a process where, when visitors comment on posts, the comment is not published directly until and unless it is approved by the admin to be posted. It manages your comments so that there is no comment spamming.
Step (1) − Click on Settings → Discussion in WordPress.
Step (2) − The Discussion Setting page gets displayed.
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.
