Yeah that's what I hate about it, the logs only shows what YOU said overall and not all the chat that happened in game, especially if the flame was coming from another player specifically. But the problem also is that a lot of people can't handle some kind of criticism or even "advice" as I'd call it. Like for ex: when asking someone to play safe and just farm up, you get considered to be "toxic" when you're clearly just trying to give advice or even help. No one wants to listen and when you question or even comment on their playstyle, they call you toxic. It's beyond stupid, like no it's not toxic, it's called trying to give you some damn advice so you don't feed the hell out of your laner and any others so the game doesn't become completely one sided. But nahh, people don't think about that when it's common sense. Just you "flaming" and being "toxic"
Also yeah, when getting banned and such they say it's 0.006% when CLEARLY it's not THAT little, at least not anymore that are toxic. Just because someone doesn't get reported as much or often as another player doesn't, doesn't mean that they aren't toxic. Just that other people don't report someone who doesn't talk as much. Like I can question someone's gameplay, and they respond with "STFU" and report me, and then I go to question/comment someone else or so, then that person reports me also. Then boom, there you go, I'm labeled as toxic/a flamer. How stupid is that.
Riot needs to have someone who KNOWS how to use common sense or even their brain to just look at these chat logs/reports and not just ONE side of the story and punish one person. Because if it was up to me and it was my job, I'd listen to both stories and look at what was said throughout the game, not just who typed more or swore more etc. But like stated before and again, they don't give a damn. Only the money they make because they'll keep making money even though someone gets banned permanently, most likely that player will make and start a new account and end up using money again to get RP. The cycle continues. Zzzzz
