most toxic thing witnessed

In a ranked game 2 days ago I was playing ezreal and my supp was thresh. He "tried" to counter gank a k6 and he died. He said "f*ing team" and just stay in our jungle all game. We won the game after 53 minutes. He was lvl 2 and put in all chat, gg ez game, carried by me. It was a x9 report for him. Hope that his account will be banned for that thing.
The other thing is just a normal, people verbal abusing all day. I play in LAS so nothing strange in that
