Is Azderaki Making a Mockery of the Hindrance Rule?
Shouting "Come on!" or "Allez!" prematurely because you think you've hit a winner is hindrance.
Grunting in pain because you have cramp is, apparently, hindrance.
Screaming as loud as a jack-hammer to put your opponent off, however, is perfectly fine.
It seems the only instance in which Azderaki won't call hindrance is when a player is deliberately trying to hinder her opponent.
