Some days ago I got a mail pointing out the dangers of networks. The mail quoted the attack to the use of social networks such as Facebook, Hi5, Myspace, Sonico, etc. carried out by Televisa.
Televisa said that social networks are not safe because they provide information to kidnappers. The Mexican journalist Joaquín López Dórigo criticized the security measures of social networks due to the kinapping of an important businessman’s daughter. A video about facebook came to the e-mail I mentioned before which I found really scary.
