I tend to spam the hell out of my nuke button when I'm playing a single character, let alone when multiboxing and I know that they aren't quite perfectly in sync. Manually spamming the button certainly does not get around the GCD, but I'm sure I'm within 200ms of it at most. I would think it would be difficult differentiate this from a cleverly programmed automated system.
Your timing is a lot more random than an automated system would be, unless it was programmed to include a random delay. It would be pretty easy for Blizzard to monitor the timing of your keystrokes on the client side and buts you for botting if they don't look random enough. In fact, I'd be shocked if they're not doing this.
