What's the real impact of the Facebook Privacy Policy and them having access to your data, camera roll, messages etc.? Do they sell your data to third parties?

Facebook started to enforce the Privacy Policy in Europe in November. (Before, they were forbidden from collecting any sensitive data from their users, and so that the data was relatively safe) Ever since this change though, I still haven't decided if I really want Facebook to have access to my data, and as per their privacy policy also my camera roll, messages, and pictures.



So I'm wondering, how bad is this? What can be actually done with my data if …
