The thing about golf that is different is golf and any other sport is this is the only sport where you are required to call your own penalties. I do agree that fans shouldn't be able to call in, but then again the player should have called his own penalty. Rules officials main reason it to be there for rulings before a shot, not to call penalties of pleas but will if needed. The bigger issue is the number of rules that have lots of grey area.
Funny part is Tiger actually indirectly caused his own penalty. They were looking at the drop, and had determined it was close enough, until Tiger said he dropped in further so gain an advantage.
