How do I stop comments showing on newsfeed?
Your comments don't have their own privacy settings separate from the posts or photos they're on… You can't hide a comment on Facebook and make it visible to fewer people than can see the content that it's commenting on.. Your only choices are to delete it or leave it visible to whoever can see the post or photo.
What is the feed filter bar on Facebook?
The feed filter bar will let users toggle between algorithmically ranked content, most recent posts and updates from their favorite friends and pages they follow.
