If you want to scout an enemy when he/she is starts to attack you, you can send all of your scouts to his/her village, maybe you can see if the hammer is in the village or your scouts may die too, it's a risk and it's the real gameplay, or some of your kingdom members upgrades scouts to level 20 and trains as much as scouts and have a duty to scouting enemy villages during attacks, this is the strategy and this is the gameplay,
But you want to use this bug and abuse it agaisnt your enemies, i understand you too, you may be right for your interests, but unfortunately, this is not a common interest for whole community.
