I saw this post in Facebook today:
To all my contacts, friends, I request that: With the recent
changes in FB, now one can see things from people who are not
in your contacts list. Just because a contact of yours makes a comment or "likes" in some activity of that person. I do not want people to contact me, and would like that they not read and see all my comments and stuff. But I can not change this myself because facebook has configured it this way. But you can do it for me. PLEASE place your mouse over my name above (do not click), a window will appear and move the mouse on “FRIENDS" (also without clicking), then down to "Settings", click here and a list will appear. Click “COMMENTS & LIKE" and it would thereby remove the CHECK. By doing this, my activity amongst my friends and my family does not become public. A Thousand Thanks! Paste this on your wall for your contacts, if you care about your privacy.
