Yep. There are also a bunch of Theramore citizens that can be seen chained up outside Orgrimmar's gates during Siege of Orgrimmar. Some are dead in cages, some are impaled on spikes, and some are alive but chained up (I'm not sure if Horde players see that, but Alliance players definitely do). And those were just Theramore citizens, not military. So the "well, it was a legit military target, civilians die by accident sometimes, shit happens" argument doesn't really even work there. The Horde captured these people, chained them up, and had fun with them. And Garrosh had to be 100% okay with that (unless he just wasn't aware that it was going on at the front gates of his own city, which is a hell of a stretch).

iirc, there was also group of orcs going through Theramore's ruins looking for survivors/loot after the bombing, and they came across Jaina. They didn't know who she was and thought they were going to have some fun with her. They learned (the hard way) who she was shortly after encountering her.
