"It's not botting, it's AFK training"

3)Grinding "mindlessly", albeit repetitive, is not botting due to your physical presence being there, and being aware of what is going on in the game.

With pet auto heal and keydown skills, people could hold down the key while, let say watching a movie, and not really pay attention to the game. That would be considered botting, so its not just the method, but you have to be actively playing for it not to be botting. I think thats the simplest definition by these standards. If you are not actively playing, its botting.
