I think what the OP is trying to say, is that Fackbook (as the custodian of our private data) should make available a list of resolved exploits such that we may be aware of potential data leaks.

Eg - up until today, and for who knows how long, photos you thought were private may have been accessed by undesireables.

Yes. In my opinion a website that is open and honest about its caring about privacy would do that.
