Maybe we need a voting system. Users can mark dupes, errors, and a course of action recommended. delete or include in the bbs layer. A script could then delete the duplicate attachments.

One thing we should do though that would cut down the problem to 1/10th of the size is limit new users from posting attachments till they have at least 25 posts under their belt.

How about this too. He he, You post a dupe you are fined 25 more posts till you get it before you can post another attachment.
