I don't find it creepy because no person in FB doesn't actually know it is me, to them I'm a number in an algorithm. The only way it could become creepy is if they publicly associate my name with the actions and start displaying this information publicly, but I trust them not to complete suicide by taking that action, just like I trust that my ISP won't post all my info somewhere with a history of all the sites that I visit.
