Moving the mouse to slot 1 to slot 2 of the inventory takes, for example, 0.1 second. Moving it to slot 28 from slot 1 would possibly take longer than that. So what you and other AHK users fail to grasp is that you can't fairly equate a single key press to various mouse movements that require different time/energy consumption - this is a big difference in the long haul, as our beloved AHK users know. This is what you're asking the OSRS team to regulate.
AHK commands are 100% precise and instantaneous, something near majority, if not all, players would not be able to do with a mouse. AHK users have been so deep into this "AHK is perfectly normal, there's not even an argument" mindset that they fail to see how unfair this is, especially considering it is a paid OSBuddy feature (and probably other clients). This is the reason the team currently still allows operating system AHK's.
I agree with ModMatK and the team's decision to at least ban paid AHK's. They'd love to ban AHK altogether, but it's not a risk they're willing to take at this time. I believe ModMatK not understanding what Aubury explained is not because he doesn't understand it, it is because he doesn't want to understand. MatK's problem is with the entire idea of AHK being wrong and unfair, so he doesn't care about exactly what the OSBuddy AHK does and doesn't do. AHK users have been using AHK for so long without question that they feel they deserve to use this - it's a privilege the OSRS team has been allowing for this long.
Every and all AHK types should be restricted and bannable; but because its use have taken over the majority of OSRS players, it now seems like taking a toy from a toddler that never belonged to him in the first place.
Lastly, I want to add that the OSRS team should have paid more attention to easing certain mundane tasks on the official client such as allowing a "drop-all" option, this would have prevented people from turning to OSBuddy and other paid AHK. But the team was unable to do this because its size is small and their priority is new content updates. We can hardly wrong them for that.
