Privacy Settings & Online StalkingIf privacy settings are not set, your info is available to anyone.Ex: You post an update saying you and your family are going to California for the week. Without privacy settings, anyone can see the post. With a basic phone book or the internet, they can find your address, and can then burglarize your home while you are gone.Additionally, online stalkers can use this information to find out where you live, go to school, eat out, and shop.Set privacy so only friends can see your profile. Group friends into categories; give them their own settings for what info they can see. All social media sites have privacy settings. Under no circumstances should your profile be open to everyone.Be wary of friends you accept. Do you know them in real life? Are they a friend of a friend? Know who is looking at your info.
