is farming useing a macro cheating

[Kanash]

A macro to do the things you describe wouldn't be possible with the in-game macro feature as they're limited in length. That means you must be using a third-party tool of some kind which is already a bannable offense on its own regardless of the fact what you suggest is essentially botting.

This.
Even if your still sitting at the PC, using third-party macro software, is still bannable.
And yes, this also includes the macro software that comes with certain keyboards, such as Logitech G15 and G19, so be carefull with thoose.
