How do I make it so one person can't write on my timeline/facebook wall?

[Dust Bunnies]

I have one friend who just writes way too much on my facebook wall/timeline. How do I make it so she can't write on it anymore?
Thanks for the advice Leanna, but I'm asking how to actually do it, because I've been told there is a way.

Either tell her to stop or unfriend her.

You can stop everyone writing on your wall, but that's pointless. I would suggest adding her to the "Restricted" list (go to the friends on the side where the lists are, click more and then restricted.) Your friend will only be able to see your public profile, so assuming only friends can write on your wall, your friend wont be able to, as she will see your public profile and anything you make public.
