That’s mainly just the way the backend and UI handles the post, the thread and replies are still there, admins and mods can still see it, it just errors for users. We could potentially modify the Lemmy software (or it could be changed in an update) to allow viewing the deleted thread with the post saying *Deleted by User*
just like it does with comments.
Yeah that’s why it would be good to make deleted threads still show up for all users, they would be unlisted but the comments would all still be there.
It used to be that this would also happen with comments both deleted and removed but this functionality was changed and comments which are deleted or removed no longer error like that.
