Discourse already automatically removes orphan unreferenced uploads. Why not expand this functionality and erase uploads from deleted posts? Only staff members are able to see deleted posts and that is very useful. But is it really necessary to keep all the files indefinitely? As administrator I really don`t care about 2 years old deleted pictures. Some of which may even be right out against site guidelines.
It would be nice if Discourse would automatically delete these kind old files and place some kind of text block in the place of deleted file. So that it would be evident that file deletion has taken place.
For example all year old uploads which are referenced only in deleted posts would be automatically deleted.
