Unless it's stated somewhere I have never seen, it's not against the rules to ho in ma.
Stop crying about it and don't put yourself in a position for it if you don't want it..
If you are in a turny plane or have your buddies around you and you see a lone g2 with gonds coming your way, please expect my ho..sorry my first choice is not to turn fight lol
Anything outside 11 to 1 is not a ho, many not seeing the angle correctly on their fe will complain it is..
If you are alone in any plane and a 109f4 is headed your way, I will not ho
Unless the setup is non ho - see MNM where planes pass by head on all night as hoing is not tolerated - I expected it as it happens more than it doesn't
