I read them...
"A few examples of what will never get through moderation: 
- Britney Spears or other celebrity wallpapers (see note about copyright above)
- Bryce art, unless the result is so astonishing that one could never tell it was done in Bryce. 
- Dolphins, palm trees, metal spheres or other over-used elements 
- XP-related walls, unless really innovative/original. 
- Copyrighted photos/images 
- Confused composition...eg...3D artwork with conflicting light-sources belying the form. 
- A ground-swell of negativity from a significant number of admins."
Yeah, because this kind of art work NEVER makes it into the wallpaper section.
