Lack of privacy then leads to security concerns and possibility of Identity theft. When information such as name, birth date, address, mother’s maiden name, children’s name, pets etc is available to all then users are basically calling for trouble. People don’t realize how important this information is. On top of this people like to check in from various locations….for example an update like “Off for my vacation to Las Vegas!!!…Excited” clearly reads my house is empty for few days. You might as well put up a board outside your house announcing “I am not at home”!!!! This is a clear invitation for thieves and people who have ill intentions.
