I often am in the situation where I combine Facebook's "friends of friends" visibility with the "hide from" option. I see this more as an act of courtesy than secrecy (in which case I would use "friendy only"): i.e. I simply don't want to clutter their status updates page with stuff they're not interested in.
For example my business contacts are probably not interested in my views on some kid's movie I just watched with my son. Likewise I don't want to bore the hell out of my drinking buddies when posting some highly technical stuff. ;) Then there's of course the somewhat awkward case of the "friends" that you don't really want to involve in your lifestream for whatever reason - yet there might be no reason to hide the posting from the greater public in general.
Now I'm interested how this actually plays out beyond that first level...
So, when I set an item's privacy to "Friends of friends" but at the same time hide the item from certain people, will the exclusion propagate to friends of those excluded friends? If yes, what happens if those people are also friends with a friend of mine that is allowed to see the item?
- I am friends with John and Jack.
Bob is friends with Jack but not with me.
When I use "friends of friends" but exclude Jack, will Bob still see it?
- What if Bob is also friends with John?
