Think I found it for those interested. No one can subscribe to me now...

What this will do is remove your updates, postings, etc. from the scrolling ticker of anyone that is not a mutual friend/fan of the person you are commenting too. For example, if you and Sally are both friends with Bob, you will get a little notification when Sally and Bob are chatting on Facebook. Sally and Bob will not get a notification when you are chatting with someone they aren’t mutually friends with. Obviously, if you want subscribers, this won’t work for you and you will be sending out your activity on the little scrolling ticker. If you are like me, and apparently many of my friends, and you don’t want your every move known, this will work.
