It’s been that way for as long as I can recall, as long as I can recall, it never deleted right away, I remember when an admin needed to approve of removal before a post was deleted.
It’s always possible to edit your post down to as little as you like as long as you have some content. Thus, I could edit this post down to “Post edited” and be done with it.
if you edit your above post down. we can still see the original via the orange “pencil” edit button top right of the post. (next to the time since posted timer)
It seems though that if you edit fast enough, it won’t show it as edited.
I always thought of it as “batch processing” that occurred in the wee hours of the night, like what used to happen at work, so the “deleted” remains visible until the system has processed all the night jobs.
I wish life was like this so I could just keep all the good parts and cut out what I don’t like. Ok I think I’m going to scroll back to late last night…
