!Hubzilla Support Forum When the date of a post is postponed, it cannot be edited until it has been published?  Can you confirm it for me?
  
I had the same problem some time ago
  
Maybe this kind of posts could appear only in the owner's stream and maybe with a different color, so that they are easily recognized.
  
It doesn't appear anywhere, neither real nor spectral, it's literally a ghost post :-)
