It's a personal insult to call a couple of (unknown?) posters a jackass? A warning? I mean, if you have to play connect the dots to see who was insulted it's really not a personal insult. Face it, connecting the dots is an advanced skill set for many dopers, so I doubt the jackasses will be known let alone shamed.
