Social networks have certainly managed to link people more effectively in the network, with the number of positive elements involved that: thanks to Facebook we have known of the evolution of former classmates who had lost track thanks to Twitter have been closer to those who admire or has helped a lot LinkedIn journalism and today we have a great tool for networking or locate relevant people within a corporation.

Unfortunately and like everything in life, where there is a great common good and progress for society there is also a dark side that overshadows and produces a range of threats and consequences that must be addressed not to cause damage greater. In this respect, social networks themselves are not the problem, but if its use for harmful purposes undeserving or for a third user.

Threats and consequences of networks

Now that we have some perspective on the impact and travel that have social networks, we can determine a whole series of points with which we should all reflect to see how we can cope:

1- Loss of privacy: in this segment have two points to comment:

• Phishing: Theft online identity or password theft spying for manipulating data and people.
• Spying on a large scale: Maximum exponent of all this we can find the “Snowden case.”

2- Addiction social media ecosystem: The fact of being connected all the time that many know not live without knowing how many followers they have, if someone commented on your photos or if an item has received more visits. These case especially those we encounter in the younger population, “digital natives”.

3- Power harassment situations: Here we have two branches to differentiate:

• Cyberbullyng: Harassment carried out by classmates.
• Cybergrooming: Cases in which adults seek contact with minors.

4- The lack of right to be forgotten: It gives much more in Google, but also in social networks cost much erase our trail creating very discomfort situations existing information or nothing that can damage the image of some people.

5- Isolation of people: The end they end up giving situations where some people are more socially adept at internet in the flesh. Having relevance on the network can make them feel comfortable and forget their friends and not enhance digital contacts.

6- Power our stress levels: The speed of events raises the pace of life causing severe stress boxes.

7- Catalyst inappropriate content

One of the most important consequences is that we all are giving too much power to companies like Google, Facebook, and Twitter … and privacy policies increasingly have to be more important as we spent much time in them and we pour a lot of personal information. The use of these data retrospectively is capital there is a healthy balance on the internet.
