Facebook graph search cannot reveal any information that the user opts to keep private, but it can reveal the information that the user shares in some unexpected ways.
Now you can know what your friends like or any information which they share. Graph search can help you find out about your friends as well as friends of friends.
All of the photos you were tagged in are now searchable on Graph Search, if the people who posted them have their privacy settings enabled to “public.”
Steps to hold privacy…….
Firstly you need to figure out who can view the information you post on facebook and for that you need to click on the lock symbol situated on the upper right corner. From there you can configure entire Privacy Dashboard and you can edit who sees your posts, pictures and profile information. You can also stop people from tagging you
