The automated system was malfunctioning. Despite cutting-edge technological mechanisms for passive detection of and active response to frequently-changing usage patterns, it simply had not been able to cope with ongoing changes. Debates raged on email threads as to how to respond. Some proposed simplifying the system; they were derided for the quantity of user input required and the probability of escalating cost when users failed to take appropriate steps.
