This is regarding a recent comment I came across on Reddit:
wanna get really freaked out? If you have Facebook on your phone try closing all the programs, then leave your phone near a radio/tv that is broadcasting in a different language overnight. I dare you. The next day, all of your facebook advertisements will be in that language. fucking scary, Facebook IS big brother.
a lot of people are missing my point, app or not this business is taking advantage of our sense of security, that's bad practice, indicative of a disgusting level of carelessness with private personal information. Specifically Facebook has given us no reason to trust them.
The /r/jailbreak link contains an unsubstantiated anecdote of Facebook giving Spanish adverts after being next to a radio.
The Forbes article link is about an announcement:
Facebook is rolling out a new feature for its smartphone app that can turn on users’ microphones and listen to what’s happening around them to identify songs playing or television being watched. The pay-off for users in allowing Facebook to microphone-lurk is that the social giant will be able to add a little tag to their status update that says they’re watching an episode of Games of Thrones as they sound off on their happiness (or despair) about the rise in background sex on TV these days.
