If they are zz Idle hubs and you have it marked under your profile as to not show up, they will not. However, as I have read, I believe, it is best for them to not show up, although it is okay, they will still harm your reputation as a writer if you do not make some necessary edits to your hubs. It is good to make edits if they have become stale and republish them. Also, I have read if your imagery or photos are not good quality, they will not show up under the choices to pick from to place in the highlighted area on your profile page. Go under your account under statistics and look to the far right of your hubs, if there are any zz, that does means they are idle hubs. You can also go to the Learning Center to read up on it.
