Most of us actively seek to protect our privacy but once we subscribe to the likes of Facebook, Twitter, Instagram etc then we are well and truly compromised, run a website or forum and connect that to the above App's then you might as well forget all about anything private, sad state of affairs but that is technology for you..
I've checked mine, and it was all very innocuous. But there's a reason for that. I am ultra cautious about what I allow to sync across various devices, about settings and so on. I work in IT and have a good level of awareness of how easy it is to let your personal data leak. It is so incredibly easy to allow data to be shared with Facebook, the various Google tools, other social media and so on. Every time you install an app or set up a new device there are innocuous looking buttons to press. These are what tells your devices to share stuff. No warnings, no 'do you really want to share that stuff' messages or anything. Before you know it your life history is on Facebook, as well as all the other social media you use.
If you've only deactivated your account, you can reactivate it and request your data. If you have deleted your account completely, then your information should also be deleted. How you would check this in principle, I have no idea.
I never cared for or trusted antisocial media. I only made a business Facebook page after being nagged by so many people. I think zuckerbum is a spoiled child. I especially refuse to use twitter. I think a medium with severley limited characters undermines the foundations of thought. Additionally, the worlds biggest moron in power frequents its pages. A worldwide boycott would do some good.
Given the profile of this, I'd be telling the papers that FB have phone calls recorded as well. The Guardian's just done a nice interview with Christopher Wylie. I'm sure they'd love to break the phone call story.
