That's pretty bad, but it hasn't caused actual emotional and physical harm to an actual living creature, or wants us to believe that he did. FOR FUN. It's debatable that kalphiter/computermix/okiver have caused monetary damage to Badspot, but that's it really.
Of course it's disgusting, of course it's emotionally and physically crushing, but in the grand scope of things it's just some guy harmlessly saying that he boinked a dog (that may or may not be true) on an internet forum. Besides, literally everyone here cracks jokes about 9/11, Riddler, Ebola, CIA, etc. where thousands upon thousands of people have died, and those are stuffty things, but talking about it is harmless.
