Why do you think she has her active status turned off?

She's my friend on Facebook, and just a few days ago, she turned her active status off. Before then, she always had it on. Now I don't know when she's currently on Facebook, but I've happened to see a few comments on her posted only minutes from when I see them, so I know she still uses FB. And she does share posts, too.
