Friend got reported twice in a row, by the same people.

My friend and I were playing a game, and out teammates (Who we now call the Trio of Trash) got mad at us. After game they reported us for verbal abuse. Next game, they were on the enemy team. My friend is chat banned so he can't say anything all chat. After game, he got reported AGAIN. He didn't say anything, because he couldn't, and yet the trio reported him AGAIN. If this is acceptable, then I don't know what is.
