Social networking sites have become an experience that makes it unforgettable for the ones who are hooked up to it. These sites link billions and billions of people with each other, with a click of a button. One can view pictures and send wishes on different occasions.

However, these sites rely on the willingness of people, who desire to share their personal information or try to expand the list of people they know or would want to know.

People, who choose to become members of these social networking sites, have given the sites a strong international reach that attract users, aged between 7 and 70, or in some cases even above.

Although, all this seems to be striking and nice, there are some shortcomings and negative aspects of these networking sites.

Seeing the vast number of people, which these sites attract, has at the same time concentrated large amounts of information, telephone numbers and addresses and details.

This poses a potential threat to the privacy of people who have accounts on these sites.

Data protection establishments from numerous countries met at a teleconference this week to talk about how they can work jointly so as to guard what they see as a solid erosion of privacy, and the European Union is also working upon the same concern.
