hubzilla won't delete-activity-inbox on server 2 server communication (activitypub w3c compliment)
I made a post on mastodon, people got it on hubzilla... I deleted the post on mastodon.. hubzilla did not respect the federation and kept the post online.
The side effect of receiving this is that (assuming the object is owned by the sending actor / server) the server receiving the delete activity SHOULD remove its representation of the object with the same id, and MAY replace that representation with a Tombstone object. (Note that after an activity has been transmitted from an origin server to a remote server, there is nothing in the ActivityPub protocol that can enforce remote deletion of an object's representation).
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
