Can they tell the difference between a lost connection and someone rage quitting by pushing the WiFi switch on the 3DS? When we play Mercenaries 3D, I get an error message when something goes wrong. Wii U has no such switch so unless a person is using the USB Ethernet dongle (all three of them out there), a rage quitter would have to unplug the router or modem. That might be too much work while angry. Of course, there's always good old fashioned start + quit which is easy to detect.
