Okay riot I'm really pissed off of your system, yesterday me and my friend were playing against a player that was verbal towards our national base and was flaming for the whole game and after the game we reported him but he did not get suspended, but my friend that was defending himself even from my own team and was 0 flaming got suspended. And now he uninstalled the game and said he will never play again, thanks RIOT... 
The system doesn't use context so "defending" yourself is viewed the same way as flaming.
Instead of retaliating in future, do the /mute all functionality in game and communicate via pings.
we reported him but he did not get suspended
How do you know he didn't get punished? The notification for IFS is pretty unreliable these days. If he didn't get a ban, he might've received a chat restriction.
but my friend that was defending himself even from my own team and was 0 flaming got suspended
If he got punished he said something that the system took as an offensive way of communication. You guys should've just muted and reported instead of trying to argue with flamers as that never really goes well.
Welcome to Riot's fanboi forums. Don't try to expose your case here. People are biased, and mostly fanbois, they don't understand that we're humans and sometimes we get tilted when a troll is harassing and insulting you. You must act like a machine, pretend nothing happens and just hit a report button after the game.
