Getting random reports?

I am not sure what is happening. I barely say a word all game and i get reported for verbal abuse? The only thing i said that you could classify as negative is F i got the wrong runes and masteries. From then on I carried the game, Lulu said stop turret diving,(Also this was ARAM) even though it was getting me fed. (I wasn't feeding, trust me, I carried the game Went 19/10.) Maybe they were annoyed at me? IDK what has been happening. Its been happening more than normal WARNING I am like ?? I didnt even talk? Is this just people getting mad and reporting me? Can this get me banned?
