It is a fact that controlling personal data in the age of social media is not the easiest - and many are surprised to see how much material there is for them e.g. on Facebook.
It is no coincidence that "Big Data" is already used for purposes of targeted communication for various (advertising, election, etc.) purposes, raising questions about the ethical dimension of the whole issue.
The question, however, is: If we really knew how much Facebook knows about us, would it really play a role? Some tools attempt to answer this question.
In 2013, Facebook launched a feature called Graph Search, which was essentially a search engine for the content that users have on the social network. Its capabilities were enormous, as, according to a related article on Motherboard, it allowed users to find, for example, photos of all the free women that a particular friend liked.
As it is noted, Facebook "silently" removed it from the forefront, however it is still functional, although few use it, both because it has been forgotten and because it is complex and because Facebook does not promote it very much. However, Eddie de Choceller, a Belgian "ethical hacker" - as he describes himself - has created a web interface that allows anyone interested to use the Graph Search features relatively easily.
This particular tool, called Stalkscan, which can be found here, aims to show users how much information they publish about themselves, possibly without realizing it.
The user just needs to copy-paste the link of a profile (their own or someone else's) and from there, through Stalkscan, can perform detailed searches with specific criteria, without violating the privacy settings of the account ( commonly, what this account has "closed" will not be visible). And, therefore, you can remember things you did on the social network that you had forgotten.
Stalkscan is not the only tool of this type: Another is Data Selfie, a browser extension that analyzes what the way Facebook uses shows about a user's personality, e.g. political views, interests and issues that interest him.
According to a related post by Mashable, this tool shows the user how to interpret his / her personality / create a "profile" for him / her through his / her Facebook activity.
If you find that you do not like how many are online for you, you can make the necessary privacy settings or, much more simply and effectively, start watching what you do and what you upload online.
