Whenever we add a new friend, this activity gets pushed to the newsfeed of a random subset of our friends. This seemingly happens even if our friends list is set to private.
Is there a way to keep our own friending activity private, and it to be pushed out to our friends?
I found also this discussion on facebook: How do I stop my recent friend activity from appearing on my friends' newsfeed? , and it seems that these guys found no solution as for now.
