Using social media Web sites is among the most common activity of today's children and adolescents. Any Web site that allows social interaction is considered a social media site, including social networking sites such as Facebook, MySpace, and Twitter; gaming sites and virtual worlds such as Club Penguin, Second Life, and the Sims; video sites such as YouTube; and blogs. Such sites offer today's youth a portal for entertainment and communication and have grown exponentially in recent years. For this reason, it is important that parents become aware of the nature of social media sites, given that not all of them are healthy environments for children and adolescents. Pediatricians are in a unique position to help families understand these sites and to encourage healthy use and urge parents to monitor for potential problems with cyberbullying, “Facebook depression,” sexting, and exposure to inappropriate content
The creation of sites like Facebook, many people are giving their personal information out on the internet. Most users are not aware that they can modify the privacy settings and unless they modify them, their information is open to the public. Sites such as Facebook and Twitter have grown popular by broadcasting status updates featuring personal information such as location. Some applications border on "cyberstalking." This has redefined the role of Internet privacy as overlapping with that of security.
Some applications are explicitly centered on "cyberstalking." An application named "Creepy" can track a person's location on a map using photos uploaded to Twitter or Flickr. When a person uploads photos to a social networking site, others are able to track their most recent location. Some smart phones are able to embed the longitude and latitude coordinates into the photo and automatically send this information to the application. Anybody using the application can search for a specific person and then find their immediate location. This poses many potential threats to users who share their information with a large group of followers.[5]
Facebook "Places," is a Facebook service, which publicizes user location information to the networking community. Users are allowed to "check-in" at various locations including retail stores, convenience stores, and restaurants. Also, users are able to create their own "place," disclosing personal information onto the Internet. This form of location tracking is automated and must be turned off manually. Various settings must be turned off and manipulated in order for the user to ensure privacy. According to epic.org, Facebook users are recommended to: (1) disable "Friends can check me in to Places," (2) customize "Places I Check In," (3) disable "People Here Now," and (4) uncheck "Places I've Visited.".[6] Moreover, the Federal Trade Commission has received two complaints in regards to Facebook’s "unfair and deceptive" trade practices, which are used to target advertising sectors of the online community. "Places" tracks user location information and is used primarily for advertising purposes. Each location tracked allows third party advertisers to customize advertisements that suit one’s interests. Currently, the Federal Trade Commissioner along with the Electronic Privacy Information Center are shedding light on the issues of location data tracking on social networking sites.
