Question regarding multiclienting "exploit"

Hello,

I was reading through this thread and had a question regarding multiclienting. Are you allowed to use one set of controls to move/attack with multiple characters, all at once, at the same time?
As an example, when you open a 4th client while 3 clients are active, all your clients will all move at once. Are you allowed to maneuver your characters in that manner instead of cycling alt + tab to press skills/move per individual client?

I assumed that it WAS illegal, but now that I take a closer look at T&C, there is nothing stated that prevents people from doing this. T&C Section 2.6, "Precedents: Client" has the closest wording to preventing people from doing this, but even that is vague. Section 2.7, "General Botting", does not have anything related to this.

My hope is that it IS considered illegal as it seems so far away from what people consider to be Maple. But that's an arbitrary line -- some people may think Multimaging is not Maple, Leeching is not Maple, etc. Therefore, my opinion is not that important. But I still do want to know ASAP so that I can do my best to adapt if it is legal. Thank you.
