Just for everyone's information, a friend of mine from their OC offices helped me ask around on their stance towards macros (be they via 3rd party software/scripts or through programmable mice and/or keyboards) and the response has been no it is not allowed.
Whether or not they can detect and/or intend to ban people over using such macros I do not know. The risk is yours to take.
