And why have there been no responses from the site moderators about one of their own verbally abusing a member? Stating something about how you think the moderation is faulty shouldn't result in name calling from a site rep. Period.
Shame scarcasm can't be seen in words or you would know that I didn't call you retarded.
Addressed. Guess you missed it. 
A site with 4.5 million members-20 of those with a very long streak of NO PPE's. 4 or 5 of those 20 make up the majority of the last 100 walls posted publicly.
You do the math-what are the odds that with 4.5 million members, 20 people represent good uploads and the other 4,999,999 people just suck at art? And what are the odds that 4 mods can judge the tastes of 4.5 million peoples insight on whats "good" and what aint??
The answer is simple. They follow principles in how they moderate. See the excerpt below from the Wallpaper section of the Upload Guidelines:
Note that "rejection" and "sent to personal page" are not equal terms. Rejection means "not posted anywhere."
WinCustomize has a moderated wallpaper gallery. That means all submissions, with the exception of Journeyman and above, are placed in moderation and selected submissions will be made available in the public gallery. If a wallpaper is not accepted into the public gallery, it will be placed on your personal site on WinCustomize. Rejections will only occur if the piece violates any of the said rules such as ripping, copyrights, etc.
Our guidelines for judging wallpapers on aesthetic grounds are difficult to be specific about. The prime directive for wallpapers is that they must WORK as a wallpaper, in other words the design should be an effective desktop background, which includes: The background is not too busy and icons are easy to see against it, Colors are not too bright to be distracting, and colors work well together. There are many subjective design related preferences we all have and some objective qualifications as well, such as the quality of the rendering and the resolution size offered. And then there is the composition, the subject matter, the overall balance of the design, etc.
Probably the best way to decide what we like to see in a wallpaper would be to browse through the section and look at what has been accepted. We recommend to everyone submitting wallpapers to try to only send a piece after living with it on their own desktop for a while first. Put as much work and critical evaluation into the piece as you can before sending it to us.
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...e.g....3D artwork with conflicting light-sources belying the form.
- A ground-swell of negativity from a significant number of admins.
Rejections:
Items rejected are called exiled. Exiling means the item is being removed from the site for infractions of the sites guidelines
If an item is rejected please refrain from posting questions about as to why in the forums, as generally these types of posts and answers can be embarrassing for all involved. You may PM a Mod and request a reason or help if you did not already receive an email detailing the cause of the rejection.
