The admins of customize.org did hide some wallpapers through the last days. The reason for this is the resolution of the submitted wallpaper and copyrights.
If you submit a wallpaper submit it in usable sizes only (you may add a preview version if you want). If you use 3rd party graphics please note the original version and license to use that resource.
Great to see so many good looking photo walls and screenshots on Customize org!
