Can we not have the game automatically warn you about your behavior every time you get reported?

So we start off in champ select and my team announces there intention to play yasuo bot. now i want to actually win so i ban out yasuo well it turns out they are a premade 3 who lose their minds at me banning yasuo and proceed to wish every bad possible thing they can think of then announce they will troll me if i do not dodge. I Don't so then they said we will all report you and get you banned. So in game i purposely remain very friendly and polite and do not react to their non stop raging in all chat and trolling in game and eventually just all mute because its annoying. the game ends before 20 and we go into post game and almost immediately it pops up with behavior warning.

like for real is there a way for it to check before just randomly handing out a warning basically saying hey the trolls did not like you yeah i know they didn't thanks for just reinforcing the bad taste in my mouth. maybe have the system check the logs first?
