Just got a warning after a 3v3 game because enemy team and one of my afk teammates reported me...

I played the game until the end with an afk diana who happened to be 4-0-0 Diana somehow convinced the other team to report me for toxicity even though the only toxic thing i said was to report diana for afk? They said I "trolled all chat" which I hardly talked in and reported me for toxicity while i had an afk diana sitting in the fountain for 2/3 the game who they praised.

Meanwhile the enemy team trolled us and called us noobs for losing a 2v3 (one of these players being a full division above us in the first place) and then reported me and I get a notification after the game that warns me to watch my behavior.

I will admit I rage sometimes but I feel like in this instance it was totally unjustified and am disgusted that I'm at the mercy of a team of trolls and an antagonistic teammate.
