Don't know if you're being sarcastic but watching YT's on 4um does not add any bandwidth usage to the site's hosting service. While the vid may be playing on/through a 4um page, the video stream data goes directly from YT's servers to your browser and does not pass through the 4um site in any way, even though it's watched in a frame on a 4um web page.
