THE PROBLEM OF SOCIAL NETWORKS

    Currently, the majority of people use social networks such as Facebook, Twitter, Instagram...  They are very good to communicate quickly with your friends and persons that live far, saving many money and time. If you have to do a work for school, you can do it through social networks.  Furthermore, you can be informed about what are doing others and where are them.
       Likewise, they are a big problem in the world, because they're very dangerous. If you publish a photo or a video in your profile of Facebook, par example, all the world will see this publication. There isn't privacy. It is bad because all people can see you and your friends and you can be controlated by someone who can be an attacker or and rapist.
If you publish a photo or a commentary telling that you and your family are on holidays, also can be very bad, because a thief can read this and stole you.
