The problem can start when you enter your information in sites like Foursquare which is linked to your Facebook account. You allow other persons to access your information as you make them available through the sites you use. So the longer you use your cell phones, the more you make yourself accessible to others.
The recently discovered mobile app “Girls Around Me” has been used for stalking with girls. The app provides a map of the vicinity. Using Facebook pages, the app provides the girl’s name, her birthday, her school or workplace, her friends, and any other information given in the social media site. It can even track how the girl looks like.
In recent developments, Foursquare has cut off its access to the app but the developer said it would continue to squeeze the app and reintroduce it later.
