How safe are we? Security risks of the social networks

We are witnessing an extreme proliferation of the social networks, which can be seen in two ways: an expansion of social network websites, and an increase in the number of people who are starting to use them. The author describes the risks associated with social networks, mostly associated with user's privacy, and the responsibility for those risks. This paper also analyses whether the rules proscribed so that social network providers can distance themselves from possible abuses are really designed to help the users be safe.
