I write the following article based on the story I read a while ago. I will not dwell on the fact, how much this may be, I will dwell on the fact that it can easily happen, it certainly has happened and it certainly is still happening!
Lia Palmer and why phenomenon.
First of all, there is no Lia Palmer, it's just the name someone has invented to set up this whole story, if it were a movie, it would definitely keep us fixed for good.
The story started in 2012 and its victim was an amateur athlete Justin, who fell in love with a fake profile and for almost 3 years they talked every day, even on Skype in a kind of "relationship"…
Details here
I will not go into the hole to create a psychological profile of the person hiding behind Leah, it is not my field, but I will dwell on the fact that, well at the moment all of us could talk to one / one "Leah".
My point of view is that, under no circumstances should we demonize the social networks and react to extremes. Certainly in the field of security there are "holes", but there is also continuous improvement on the part of the providers, as well as continuous information (as much as we can) on our part.
First of all, it's not facebook, or twitter, or instagram's fault if our account is wide open, the only one to blame is the individual user who just never took care to be updated.
It is a human element, to push it and then ask how to deal with something. Obviously it is now too late and also, the internet is a relatively new medium and there is no specific legal coverage for everything yet. When I myself upload a picture somewhere, every intellectual right is lost.
Anyone can use it, this also applies to instagram for anyone who does not know, read the terms of use.
Second, each social network provides alternatives to maintaining a "public”Or a“staff" account.
Public account he will say that everyone sees every post, every photo you upload and every check in you do.
Personal means the opposite, not everyone sees it, only those you choose see it. Of course there is a detail here, do you personally know all your online friends? I have seen profiles on facebook with 5000 ++ friends. And this profile was updated regularly and in detail by its owner!
Phenomenon for the very simple reason that man, taking advantage of supposed anonymity, tends to present something other on the internet than he really is. Is the reason "Like"? Probably some psychological satisfaction and confirmation.
The hunt for Like.
As she says following research, many seek recognition, affirmation and much more in social networks, logically either due to some particularity of their character or reason for isolating the individual.
This recognition is supposed to come through the press of a button and the sum of these clicks for some replace social rehabilitation, how do they count on something?
I said above, it's not my domain! So I stop here criticizing why I could write whole pages.
But through the hunt for "Like", the person is led to the misuse of the social network, either adding friends thoughtlessly and without any criteria, or sharing thoughtlessly privacy for the purpose of recognition. That's how you lose the game, when someone malicious comes and does something you don't imagine, where the purpose was only to gather "Likes", you accidentally discover the photos from your wide open account and on other profiles, like the "Leah Palmer" case which I quoted above.
How can we deal with it?
First of all, each of us should read them terms of use of any social network in which it joins.
Then each network provides many choices for who can look at our profile, below, as an example on facebook, everyone can set them up.
as shown in the above path, we can select different account privacy settings.
We can also choose who will see our posts at any time as shown below.
Typically this particular mode most of it ignore. Facebook by default publishes anything "Public". For this caution.
You can also get information from here, facebook has created a dedicated information platform and direct setup.
A large percentage of users now make use of social networks from smartphone ή tablets. From there there is the risk of inadvertently sharing our location, or by wrong synchronization/selection of uploading all our photos to facebook.
In the new versions of Android 5, 5.0.1 Lollipop, by default many functions are disabled, such as that of "Location”And automatic synchronization. If not, we can turn them off. We see that operating companies are changing their attitude in this area.
From Facebook Messenger.
From the Facebook app for Android.
Enable / disable auto-sync.
End
The impetus of the time makes us become members of the various social networks.
We must not be afraid of the fact of the unknown, but daily information and control must be enforced so that the social networking can be used in a healthy way. 
Exploiting social networks can increase our self-promotion, eg our work etc. But bad use can also ruin us. So care, both what we share and who we share it with!
