Well we all know that Facebook stores a huge amount of data about you. They use it to make money among other things. You give Facebook the right to collect, store, share and manipulate this data to suit their needs.
But as a BBC journalist recently realised, what they collect can surprise and even alarm you. What they found was that Facebook was collecting all their Phone's contact database.
From their article (I will supply the link after this) is this, I feel scarey, detail:
"But then I clicked on a file called contacts. I was taken aback to find my entire contact list, thousands of phone numbers. Now this was not limited to Facebook friends and included many people in the public eye who might be disturbed to find that their private numbers were stored in this way.
I cannot remember what happened when I set up my Facebook account back in 2007 - in those naive days I could well have clicked yes when invited to upload my contacts so that I could see who else was part of this new young community. So, my fault I suppose.
Then I noticed that at the top of the list were some numbers that cannot have been sucked into the Facebook machine a decade ago because I had only added them in recent weeks. They included, ironically, the mobile number of Carole Cadwalladr, the journalist who has blown open the whole story of Cambridge Analytica and Facebook.
So this means that every time I enter a new number into my phone's database, it somehow ends up with Facebook - the company is in effect monitoring me."

Is it time to cull or control your Facebook account?
Did you realise what you signed up for?
Have you ever checked what they store about you (the infopackets' article explains the steps to check it). Maybe it's time to do so?
