Here's a though to help keep the site clean and remove stuff that is just clutter. Put a 30 day 'no view it goes' limit on items. If an item has no views in 30 days (viewing your own content to keep it active wouldn't count) the item is automatically deleted from the cue of viewable/downloadable items. If the person wants to resubmit the item that would be up to them.
