Do not log in at all during full marks. If someone gets reported the whole group gets checked and you will get banned. You can play during house pride but make sure to not earn any house points otherwise you will get put in the group and it can end up in you getting banned is someone gets reported. Dont stack to much energy as ive seen people get banned for stacking to much. Keep your energy below 100 to be safe. If you really like an outfit during full marks, if you want to risk it, log in 5 minutes before the event ends. Also, use reddit to see what events are next. Finally, never contact JC, even if its a bug.
