If you’re trying to have a cheeky stalk of somebody’s Facebook profile, but they have it set to private, and you’re not friends with them on there, the only way to do so is to use a Facebook activity log app or tracker. The apps, like the ones we listed earlier, allow you to access other people’s Facebook profiles while also enabling you to see their posts, timeline, new friends, likes, and activity on the page, all without them knowing.
