Privacy Protection on Facebook, Twitter and LinkedIn

The social networks and companies providing sites for social networking build up their wealth and popularity on the grounds of close observations of social behavior and relations, as well as on targeted advertising of various things, largely relying on the data collected on social network users and logs on their regular activities on social networks. Some of the reasons for voluntary disclosure of personal data recognized by several authors include desire for attention, disinterest or lax attitude toward one’s own or other people’s privacy, incomplete placement of information, confidence in security of the data on social networks, as well as trust in their social media friends. Violation of the right to privacy most often occurs within the social networks with the highest number of registered users like Facebook, Twitter and LinkedIn. The issues that impose themselves are whether or not social network users are still the owners of all information and whether permanent removal of a user account and deleting of the data once posted is possible at all.
