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!"
I saw a few people editing all their Reddit comments/posts with an explanation as to why the info is gone and they also gave a link to where they could find their content reposted on Lemmy. Thought that was pretty clever.
My brother you are kinda living under a rock. There have been widespread of websites/scripts to do this while the deadend(because we don't know of what changes reddit would make of their api which may hamper the work of these services)of July 1st was approaching.
Redact
Shreddit
Power Delete Suite
(The best one, which I've used) Power Delete Suite Fork
they also gave a link to where they could find their content reposted on Lemmy.
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.
