You can ask anything, keep it simple and obvious, e.g. Is the sky Green? NO!. Doing this will stop stupid bots from being able to post.
It only shows up when you are logged out, so you dont have to fill it in if your an admin. On top of this, it also adds javascript validation to the form to ensure the required fields are filled in.
