After thousands and thousands "why was I banned/punished/trolololol ???!!!?!?11oneeleven!!!" threads Riot seems to bend their previous stance on not showing punished players the cases that scored them a punishment.
So punished players, now stop crying and learn to behave. Now your wrongdoings are even told straight to your faces, so either improve or enjoy your punishments.
