Confirm that a course was deleted

dear @Joshua: would you confirm/deny that the creator/user @kinser deleted some of his courses (personally I ask abouta japanese one)

thanks

This leads onto another question I have pondered.

If I am a Contributor and the Creator deletes his account and his courses, can the MemRise team find a backup copy for us?

I would back up all the courses I support if it were a one-click build-in process (which we have requested elsewhere).

Can @Joshua comment if deleted courses could be retrieved, please?
