Snapchat is an app that allows users to send pictures to each other that disappear off screen within a set amount of time. Unfortunately, there is bullying on snapchat in the from of screenshots, sending pics without permission, negative comments and more. If this the case for you or someone you know they can block a user, tap the menu icon, select "My friends. locate their name in the list and swipe right across their name. If you would like to delete a friend from your contacts, press "Delete," even if you haven't added the user as a friend their name will appear in the "My Friends" list under "Recent" if they have sent you a message recently. If you receive an inappropriate photo or someone's harassing or bullying you, report it by filling out their online form.
