no using a keyboard with macro functions is not banable. its not a program interacting with the wow.exe in any way. its a function of your hardware.
same with the paper thing. though that would be harder for blizzard to "notice" becasue of the random timing of the movement... whereas a keyboard hardware macro would be exact intervals every time. (OBVIOUSLY if your online for 3 days STRAIGHT with it your just asking for trouble, but other than that, as long as your not ""hacking"" they don't give a #$%@)
