I'd suggest changing the link permission to "anyone can comment" instead, as any ill-intended individual can grief the file as it is now. Then those who moderate the file can approve or deny new entries.
Just did.... actually lasted longer than I expected! Someone was removing all the community links and replacing them w/ the code repo links. Restored and cleaned up. The access is now comment only to anyone w/ a link.
Honestly I'm kinda interested in seeing how long everyone behaves. File owner can always keep a backup of the file and change permission and restore if people act a fool.
