There is no automatic banning system from right-click player reports.
Why would Blizzard create an automatic banning system that is ineffective against bots, that no one has ever shown to have banned a bot; no video evidence, nothing. Why would they create a system that can apparently only be used when a large group of people conspire to ban someone unjustly?
People complain for months on end that reporting, even en masse, does nothing to remove botters from the game. Now people claim those same reports can automatically ban people.
I am not certain what you are referring to as automated. We don’t really have automated actions involved here outside of when we develop specific detections for botting programs that we’ve found.
