Is your feature request related to a problem? Please describe.
I deleted by error an outing of a contributor instead of the pictures he wanted to delete.
There is currently no way to retrieve a deleted document.

It would be good to set up a logical deletion of documents, in order to be able to correct a possible error.
So when a contributor (if he has the right) or a moderator deletes a document, whatever it may be, it would have a “Deleted” status in the database and would no longer be visible on the site.
Every year (or more often?), all old documents in the “Deleted” state would be permanently deleted from the database (via a robot?).

We need to add a “deleted” field to the activity feed cards, if it is a separate table. In order to be able to redisplay a deleted document, you must not delete the corresponding card, but only hide it.
