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.
I wanted to do the same but I have heard that reddit is censoring any mention of fediverse or migration to kbin/lemmy and hence I just edited it out (with PowerDeleteSuite fork) to some copy pasta and deleted my comments.
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.
