I agree, 100%, people should be asked nicely the first time, and the 2nd, and even the third.

What happens when:
"Please dont kill the lambs yet, we are trying to farm"
gets answered with:
"Shut up noob, i do what i want, fk you!"

Honestly, if someone told you that you were doing it 'wrong' even though you thought you were right. Would you just accept their word for it? Would you even pause your actions to consider that they may be right? Or would you keep going, assume they were wrong, and get on the defensive?
