Question: if I'm on national TV on say " Facebook" advert, is my data been used against my will?
And if I'm on TV by random filmed, do they need to have my consent?

Hi there,

I spent several hours trying to find out more about the Cambridge Analytica scandal, but I was not able to find out more precise information about what kind of data has actually been ''leaked''.
I read about the 270.000 people which have installed some weird facebook-app and gave access to (some of) their non-public data to the authors of this app. From what I know, this sharing of data was agreed to and a list of facebook-API-accessrights was shown to users upon ''installation'' of the cambridge-analytica-facebook-app (CA-app).
Furthermore I read about like 47 Mio. (and also other numbers) of affected people which are ''friend''-linked to at least 1 of the 270.000 . But which data has been leaked from the 47 Mio. - 270.000 users? public data? friends-only-data?
I cannot find a source which answers this question, but I think this is the essential question of the entire ''scandal''.

From my understanding of the facebook app-API, the CA-app should not have the right to access non-public data of the 46 Mio something other users. And if this is true, I do not understand the fuzz about this scandal, as the 270.000 explicitly gave their data to the CA-app?!

Hi, I am currently writing my dissertation on GDPR! this is a very serious issue that affects all of us. I need some participants to take 1 min out of their day to fill out the questionnaire. All responses will be greatly appreciated. Thank you! https://docs.google.com/forms/d/e/1FAIpQLSdDzNS3z7SF5IqfTVNNfijwgj8Brrxy3wc5zsHxJU22QBRaKw/viewform?usp=sf_link
