@vimkuthi, I have actually done some research on this earlier this year when I followed up on the incident where Mark Zuckerberg sold facebook data to an advertising company. The whole scandal actually slipped my mind until @crypto.piotr sent me a memo detailing the content of your post. Reading this has brought back some info that I read up on...

I did watch a few hours worth of youtube videos that was about the court session that took place where Mark Zuckerberg was questioned about his actions. It was actually quite scary at the fact that they control so much info and can do just about anything because they have enough money to pay their way out of many illegal activities. I remember so many people were like, "He's and alien" or "He is a psho, no emotion..." and that was somewhat funny. I had facebook for about 4/5 months, but it was only for playing Clash of Clans (for the friend list :D), but I deleted it because my mum posted a few embaressing pics of me and tagged me in them... So I deleted it because that was just so bad hahahaha.

I am a very paranoid person in nature... it runs in the family, so hearing all that happened I was glad that I didn't post anything during my time using the social networking site. I even went through a hectic phase covering my webcam with tape, but then realized a few months later that the government may already have so much recordings of everyone that I didn't bother with the tape.

Sorry for the long comment, but when talking about cyber security, breaches, hacking and regards to user information, I can go on forever... This was a great post, Upvoted and Resteemed :D
