A stalker can be someone you know, a former boyfriend or girlfriend, or a stranger. Stalkers may show up at your home, friends' house, or workplace without telling you or even asking if you are there. They may also send you unwanted text messages, letters, emails and voicemails; constantly calls you and hangs up; use other people as resources to investigate your life. For example, viewing your Facebook page through someone else's page or befriending your friends to find out more information about you. Another major form of relationship violence is digital violence. An example of digital abuse is your boyfriend/girlfriend viewing your social media accounts and manipulating them. Tampering with a partner's social media account is the most common form of digital abuse. More than one in twelve adolescents in a relationship (8.7%) say their partner has used their social network account without their consent.
