I think it should be enforced that identical items should not be allowed! ie: multiples of the same model in different formats, multiples of the same texture in different colors, etc. This is flooding the content area and making it a cluttered mess. All like items should be contained in a single ZIP/RAR and identified as containing multiple formats or texture variations.

 Also, I feel that any item portraying a copyright or trademark name should not be allowed. This opens the site to possible law suits by the copyright/trademark holder.
