First, you need to know the Facebook User ID (or Page ID) and you can get that easily by going to FindMyFBID.com. This will take your Facebook address and display its ID number to Facebook.
Second, replace the “000000000” with the Facebook ID you acquired above. Use this URL to see the content published by that user or page easily.
Once you do that, you’ll see all that stories that have been published by a user on Facebook unless they marked them as private or only shared among certain friend groups. You don’t need to be friends with them to see their public posts.
