If it was an accident like he was trying to qml someone at spawn while pinned behind them in spec it doesn't tell you at any point in time who you qml'ed. You don't even know if you qml'ed anyone at all. Then when you get qml'ed you hit m and all it tells him is "he was active after all, you lose a multiplier"
I am not defending his actions at all and tell you that you are wrong but it's hard to tell what his exact intent was through that screen shot.
