Like Software that shows additional in-game overlays, things mainly depend on what you actually do with AHK. FRAPS shows an overlay with a framerate counter, Steam shows an overlay with friends/achievements notifications and fps aimbots show an overlay showing enemies' positions, locking status and whether you are in view or not.
If your game has a button mashing portion and you use AHK to automate this, you are probably cheating. If you are merely controlling your camera, chances are you're instead in the right.
That said, rule 22 of the Rules of Conduct seems to be most relevant here. I don't think it applies here, but if you wanted to be 100 percent sure you would've asked a lawyer, not gamers.
Also related is point 7 of the User Agreement:
You agree not to use any hardware or software, including but not limited to third party tools, or any other method of support which may in any way influence or advantage your use of the Service which is not authorized by NC Interactive, including but not limited to the use of 'bots' and/or any other method by which the Service may be played automatically without human input.
In spirit, it's all against farming. In reality, you'll have to ask a lawyer.
I've now read the original question. If they suspend you because of that, I have a new entry for my blacklist.
