Have you even read the news of what they are doing at the moment in order to fix this problem? (according to what they said it should be fixed by wednesday)
But you're suggesting taking manpower of off fixing the problem, to do something that can be automated, not to mention the automatic AFK kick would be much more reliable, since you could go to the kitchen to get a drink, only to find that in those 5 minutes you weren't there you got kicked by a GM...
