The name of the game is winning, any mistake you can sucker them into is fair play.
Surprised to see you say that, Ghosth.
Certainly there's no good reason to abuse someone who runs to ack. There are many, perhaps most, people who agree with Ghosth's statement here. From the other perspective, though, I always feel like the runner has effectively said, "OK, I'm losing, let me go get some help."
Lusche, I didn't watch the video, so I express no opinion on your actual question!
