No excuse for losing track of anyone. Today, thanks to the social networks of Internet, anyone can keep in touch with friends and acquaintances regardless of the distance separating them or the time difference there is between them. An example of such pages is Tuenti, a social network created in January 2006 by an American student currently based in Madrid, which was initially only aimed at the public university, but given the success that was reaching, was opened to anyone who wanted to participate by requesting an invitation. Caution, user friend, however, to what extent is an advantage that one can be found and find others without leaving home? Is it dangerous exposure of some personal data with many users? Did he lose control over what third parties can do with the identity that we project onto the network? The case of Marta del Castillo has shown that sometimes the control of the content in these networks is impossible, surprisingly, even for the creators themselves, as in Tuenti. However, before condemning the media in question and make tragic events like the above named end up becoming a media circus, we should ask what is wrong and see where the limit to the privacy of users. And is that although the media have an obligation to provide an overview of the story, we must not forget that what was published on social networks should maintain its private and will not result in the display of content to third parties without your consent, regardless of the purpose intended. For this reason, it is not surprising that Icaro Moyano, director of Tuenti, and his team has already taken steps to try to curb the social phenomenon that has become the case.
