You can mail pg and ask him.  Recently there have been a few stories on HN from users saying 'why is X happening to me' where X is votes not counting, stories being flagged, comments being deleted.<p>TBH I'm just not interested.  If you've got a problem with something that's happened to you ask pg.  Don't come whining to the group.<p>And the user who is secretly emailing people about comments that have been deleted doesn't seem helpful either.  They are working in a behind-the-scenes manner that could easily end up being counterproductive as some 'anti-HN' group gets formed by it.
