How to set privacy for recent facebook posts?

[Raktim Banerjee]

I want to set privacy for my wall posts of recent activity, so that it can't be visible publicly. Public can see my wall with no post, they will see my wall blank.
I have set the option "Who can see my wall posts" to Friends and "Who can Wall see posts by others" also to Friends. But public can still able to see my 'Recent activity' posts.
What's the process that public will be unable to see my any kind of Wall post(i.e. they will only see a blank Wall)?

If all your settings are set to "Friends" then no one other than your friends should be able to see any of your activity.
