Your Page has been unpublished and it cannot be published again.You will get this message when facebook automated system will auto unpublish your pages from facebook .

You have agree on this fact that facebook is not google , facebook can delete your pages anytime from facebook , theye are not doing it manually but there automated system sucks.

If your any of your page admin or content publisher is involved in any type of spam activity then fb will delete or unpublish your pages from facebook no matter how much money you have invested on your pages , facebook don’t care about those invested money.

So my suggestion is not to Advertise your pages on facebook or at any other places.
