Is Riot gonna ever fix their toxicity issue?

Ever since making the report system automated, so many people have quit being toxic in game, but instead, champ select and post-game lobby is where they go alll out and Riot don't give a shit about that, no no, as long as they aren't toxic ingame they're good, but people are also toxic in game, some say some small things and then go all out post lobby, some just be toxic overall, but either way, those people still get away!! Also, if the system's automated, why the fuck does it take 3 weeks to finally ban someone who needs it! <removed by moderation>, a NA player was one of the most recent toxic players, but in game he didn't say anything too bad, just a couple of things that showed he was frustrated, but post-lobby he said so many toxic things to our entire team and mostly to me and my duo. He kept blaming us when he got caught out because we didn't "push mid" while he got killed at baron, but we didn't have minion waves so what're we supposed to do? Then I said report Kayn for toxicity, and he said I constantly flamed him for telling him to split then getting 1v4d. Then he called our entire team bad (mostly twitch because he was trying to stay alive instead of autoing the enemy) and called him a retarded shit. I swear I hope this man gets banned because he deserves it, not to mention he hasnt played ranked in at least 20 games. Why does it have to be so hard to report someone, and why do people only get banned when getting reported from the enemy team. The enemy team can't see the other team's chat, and they don't give a shit if the enemy is trolling or flaming, as long as they win they don't care, so they're obviously not gonna report him and waste their 3 precious seconds. I miss real human report checking, idc if it takes 2 weeks to check, as long as they're checked and get the person banned correctly. Riot's a multi-millionaire company, they can hire people
