Like someone has has stated- VMK is sort of a relief and a getaway from the real world. For many players its also that "happy place" they can go to and be relaxed. If someone died in your family I am sure they would be on, but if they weren't then again- I dont think a magic pin would be the thing on their mind
If you are failing a class you dont deserve to be on the computer or VMK at that. Your schooling and studying should come first, and if you cant keep up then VMK shouldnt be on your mind. Also Magic Pin should be far from what you should be trying to get if you are doing bad in a class. I am not sure who you are speaking for when you said this, but whoever it concerns they should get their priorities straight if they think VMK and Magic Pin(s) are more important than their schooling.
