Getting sick of seeing people grief games through actions that cannot be seen on chat and/or passive aggressive gameplay that cannot be detected only to have those toxic players get into chat after the game is over to talk shit and not get any sort of punishment...
The game has clearly evolved to a point where people know how to aggravate you without being detected by the system and something needs to done.
And before somebody mentioned you can mention as a comment to check pre chat, you still have to hope that people @ riot have the time to do this. There is no reason I can think of to not include pre and post game chat by default.
pretty sure this game is beyond strict enough, you can't even say half the shit you use to be able to say without being deemed "toxic"
Riot spends money and time programming ways to catch "toxic" people.
OR
You get over it.
One of those ideas sounds a hell of a lot cheaper and easier.
You mean the teammate and his/her friends who conveniently ban every champ you indicate you want to play just because you got assigned the role they want and you won't trade? The player who sits next to you and leaves you to die when they could help you get a kill, then goes and finishes off the enemy right after you die? The player who would rather force 2v5's than play around their team? The player who sits afk in base - only moving enough not to dc and get penalized?
The player who ignores all logical advice you shouldn't have to ask them to do in the first place only to conveniently "listen" to your advice when it no longer applies because their 8/0/0 support or mid or top is now in your lane camping you because you are the only hope of your team making a comeback? And NOW they finally stop trying to fight fed enemies and don't leave tower to shove even though they are now 1v0 or 2v1 or 2v0? Then flames you by repeating everything back to you that you told them after you die 1 time to a 3v1 tower dive that you had no warning was coming because you can't leave tower while being 1v2 camped all game?
The player who blames you for pinging 5x for team to back off and not fight or position where they can get caught out - so you can clear a side wave and get pressure before grouping with team - since you are the only one with tp?
The player who blames a 5/2/3 toplaner for losing them the game because he doesn't join half the 4v5 fights they start? Never mind that you ask them to drop a ward via chat and pings 10x, but no one does so you can't tp halfway across the map. Never mind the 4/15/7 bot lane or mid who had jungle help all game and still can't 1v1 the enemy mid or adc or support brand. Clearly it's all toplane's fault.
But none of those people get punished. While you tell someone they are an idiot 1 time because they ignored you 5x when you asked nicely for them to stop invading enemy jungle 1v3 with no wards or backup vs 3 fed enemies and 2 mia enemies. Because after the 3rd time, it isn't a "mistake" it's inting and you are sick of being flamed by them. So you are branded among the 10% most vile creatures to play lol.
yeah if some one does bad in a previous game I always have someone in my chat whining about it for example one time I wanted to play sona 
support and my adc flamed me whole game about what a "bad champion sona is just because some noodle head before me supposedly sucked at playing with her.

Riot has said that post game chat is taken into account with reports
Honestly no, that is the only place where I can defend myself from flamers who harass you all game long, because in league counterflaming, or as people like to say "defending myself", is considered worse than actual flaming, so after game lobby is the only place where I dont have to respond with "please dont be rude" "come on man stop flaming pls :)" , I mean that is what a person with actual feelings would react to and stop flaming, if I ever get mad and start flaming after I tilted and someone says "please dont say bad stuff to me, it hurts me" I will feel sorry and stop immediately. What most scum does however is flame you even harder because they like to pray on the weak. I have been bullied my whole life because I am poor and always sick so I know people. So yes, that lobby is where I get to say what ought to be said - that I hope they die in the worst agony from all the cancers, ebolas and other nasty shit because people like them deserve it, they really do. Fuck bad people.
Considering chat restrictions do not carry over from pre game and post game lobbys, I'm sure that riot is just not going to even bother implementing something in their system that will check those two things any time soon. I mean, this negative behavior doesn't even show up in the report cards.
I will see it when I believe that riot is working on adding it to the system, but right now, it's really easy to get your point across without triggering the system. it's honestly bullshit how easy it is.
example: I was just in a game where the enemy jinx had to be muted because of him being super toxic and very hateful. I reported the guy, and I don't expect rito to get off their lazy asses to punish the player
Hoping it's next on the workings tbh. Wanted this a loooong time.
DON'T STOP THERE!
Any private messages sent in game or outside the game through either the clients messaging system or third parties should also be taken into account.
