OurMine didn't mince words on the modified posts. It claimed that BuzzFeed was sharing "fake news about us" (read: it could be accurate) and threatened to make the site's "database" public if there's ever a follow-up attack. It's not clear that OurMine actually has what it says, though. To date, its 'hacks' have really involved discovering account login details -- it doesn't compromise whole servers, like you'd expect with a conventional hack. While we don't want to rule anything out, it's entirely possible that this is bluster meant to discourage investigators from pursuing the truth.
