I found a way to retrieve the text of comments deleted by user or mod. I don't think it is an issue of federated instances not respecting the deletion.

Is it a bug?

Or is "deleting" always really just "hiding"?

        Well on the bright side I was unable to retrieve the text of the original "comment 1". So it seems you can overwrite content somewhat persistently. At least superficially.
