How do post/comment deletions work on kbin vs Lemmy?

On Lemmy, comments are not truly deleted, but hidden for all except instance admins. Also, deleted comments will still be present (they just say something to the affect of "deleted by user") and still show the poster's username even after the poster's account is deleted.

Does kbin function similarly? If not, what happens when a kbin user comments on a Lemmy post and then deletes it?

Just curious. Thanks, friends!
