I'm certainly interested in my own privacy, I had gone through the privacy options in great detail when I first set up my account (and turned most of them off except to friends). And I don't allow apps access to my profile unless I trust the source. At the time, nothing much seemed to help me with regard to third party apps that access me via my friends. Otherwise how is it that those third party spam apps are able to blast me with invites and "random friend sent you a hug"s?
I note that you're not making any substantive corrections to what I'm trying to say, in favor of just telling me I'm wrong. Perhaps you'd care to illuminate *why* I'm wrong?
