Social network addiction is a dependence of people by connection, updating, and control of their and their friend's social network page.[18] For some people, in fact, the only important thing is to have a lot of friends in the network regardless if they are offline or only virtual; this is particularly true for teenagers as a reinforcement of egos.[19][20] Sometimes teenagers use social networks to show their idealized image to the others.[21] However, other studies claim that people are using social networks to communicate their real personality and not to promote their idealized identity.[22]
