A screenshot, taken way before rexxit, of two comments on reddit, dated “1 year ago”.
The first comment is by a deleted user and the comment has been removed. The second comment is a reply to the deleted comment and it says: “That solved it. Thanks!”
Edit: added temporal context.
Seems like if you edit the post the comments don’t go away even if you put Lemmy links. Maybe there’s a time delay but I edited my comments through PDS too with Lemmy links and then looked in incognito/other devices after it was done and they were still there.
