Facebook allows you to like individual posts, as well as public events and pages. Unfortunately, Facebook does not allow you to hide flags on individual user posts. However, you can remove flags from the Activity Log and hide the flags you have given to public profiles and pages.

Warnings
- Hiding their Activity Log messages will remove them from the Chronicle on the main panel. The events you like will not appear on your profile page until you share them.
- You cannot hide individual messages in this way. When reviewing your marks in the Activity Log, you can see the default settings for each message. Only the creator of a post or community can change it.
