If you’re using Instagram to keep track of your favorite people and their posts, you may want to consider blocking someone from seeing your tagged photos. This will help keep them from seeing what you’ve shared and potentially ruining your relationship with them. To do this, open Instagram and go to the “settings” tab. Scroll down and click on the “block users” button. Enter the person’s name in the “block user” field and click on the “apply” button. You’ll need to confirm this before it’ll take effect.
