Hiding comments by keywords or filtering inappropriate words prevents the visibility of words that you don’t want to appear on your page.
1.Choose the page you want to hide words for, then click on ‘Manage’.
2. In the ‘Auto Replies’ section, go to ‘Keyword Replies’.
3.Type in all the words you wish to hide from your posts in the ‘Hide Comments’ section.
Now, when a customer types a comment with the keywords that you have set, the system will hide the comment immediately. The only people who can view that comment are the person that commented, their friends, and the admin of the page.
