ok this leaves a fair problem. The ops opponent used %%%%%% as a racial abuse, the op then reported the abuse, and the op did not get a notification telling him the abuser is banned because his report because the op is not the last one that reported the abuser.
first problem is that the abuser clearly violated the codes and conduct of the game with a racial abuse and was not banned immediately!
does this no imply an inefficiency with the current report system?
sec problem if he is banned why not send an notification to all who contributed to his ban? the most disheartening aspect of league is that too many abuser are not punished, if you riot said they are but the player doesn't know about it. it really doesn't help because the player has no reason to assume the abuser will be punished. we simply wouldn't be able to tell who is getting punished and not punished.
it is like a legal system where the family of the murders victims has no way of finding out the sentence that the murders get, would you like to live in a world like that? and that world is the league of legend at its current state.
