Auto-refreshing ads

Publishers are not permitted to refresh a page or an element of a page without the user requesting a refresh. This includes placing ads on pages or in placements that auto-redirect or auto-refresh. Additionally, publishers may not display the ads for a preset time (i.e., pre-roll) before users can view content such as videos, games, or downloads.
