This guy in Oz... did that regularly... though I have never heard of him bowing. He would cheat in front of spectators, cameras and refs... there are photos of him (within 6 feet and looking straight at the camera) playing with a 3 inch diameter hits in the middle of his lenses... I never bothered to learn his real name but he went by the nickname "Abbo". The last time I heard he played was when I gave him a 2-4-1 for playing on after I had told him to get off the field when he was goggled and we ended up getting physical after the game when he got in my face and was repeatedly abusing me and pushing me... suffice to say I had split with my then wife the week before so I was not my mild mannered self and he ended up 10 feet away on his arse. I had people shaking my hand afterwards saying they had wanted to do it for years... though I was only defending myself, I still felt bad about the damage to my professionalism as a ref. Looking back though, it was a service to the sport.
