Or the player could just not swear at the ref and they won't get sin binned?
It's acting as a deterrent, not a gimmick.
I'd be interested to see how much it cracks down on it at that level when they inevitably do the analysis at the end of the trial.
Just another gray area isn't it?

Says the same the week after doesn't.
If a player swears in the refs face he should be off anyway
