Facebook offers tools that are more fine grained than unfriending. You can block someone, unfollow them so they don&#x27;t appear in your feed, or turn off notifications for the piece of content they shared.<p>Exposing more controls is always a balancing act. From a user experience perspective it can add complexity to the product, this can make it feel more confusing. The privacy setting, for example is very powerful but the UI is built so that most complexity is hidden until you need it. There is also engineering debt. Once a feature is added it is very hard to remove. A setting like hiding notifications on a per-user basis would have to stay in the codebase for all time, even if Facebook decided to stop showing the UI to new users.
