This is not exactly a rant about Facebook (or Google, or this or that) and how we are allowing ourselves to be controlled somehow, to show to everyone what we like and we don't like and so on, but at least it's something interesting.
I'll say that I have been using internet for many years and pretty much always I've tried to hide my tracks or at least, make sure I can't really be linked. I'm planning to extend it further by using a new gmail account for everything with a pseudonym (if writers can do it...) and so on. I had Facebook for a year (never again for myself) and I didn't use my full name nor my normal e-mail account. If I google my full name, only two things appear, one from university and another one from a petition online (non-political, but rather stupid). So in short, I've tried to keep myself hidden as much as I could.
However, something interesting happened that was surprising and somehow worrying. Some time ago I created a Facebook persona so my team at work could use to contact other companies or people in for various reasons. This Facebook account was created with a new Google Mail account. Just to clarify, and unless I'm wrong, both Facebook accounts, mine and this one, didn't exist at same time and I never log on this work Facebook from home. So, until here, all fine...
...but then I saw, in the "People you may know" tab, people I do actually really know. Just...how? We're talking about an ex-girlfriend (Who I had on Facebook when I still used it) and a far relative from a different country with whom I never even shared an e-mail (that I can see) and the last time I saw him was like 6 years ago. How is this even possible? From where is the information being taken? There are some more people in the tab that I know and they are not friends of my colleagues or anything like that.
What is the limit?
EDIT : I believe I figured it out. It's related to the location from where you're logging into Facebook. I've logged with personal Facebook accounts from the same computer where I log on this FB persona for the team. While the other accounts are closed down, it's possible that FB is moving the "suggested friends" list to the active FB account. Kinda crazy...
