anyone who knows a friend can see your profile stuff, and companies can see everything if you play one of their games. Anyone can add you as a friend, and sometimes people lie about their ages ect. so you don't know if they're your friend or not. You also got stupid adverts and messages apearing all the time, as well as people writing on your 'wall', so you can see their entire conversations.
Any child can set up an account and can add anyone who requests to be a friend so thats not good for child safety as we already know with stories in the papers. So an adult should set up their account and use the safety features that allow their profile to be found only by friends of friends
Facebook est le plus gros réseau social au monde, qui permet de communiquer avec ses amis, de retrouver d'anciens amis, d'échanger des informations, de faire de la publicité, mais ce réseau social conserve également trop d'informations personnelles sur les utilisateurs, qui peut nuire à leur vie privée !
