The life of a jungler

My mid goes 1/9 (a fizz, who woulda thought) and blames me for it cause he would dive a Le Blanc and Fiddle sitting under their tower, and would ping me to dive when I was less than 50% hp. He then proceeds to flame me and say "I'm going to get you banned" for reasons like I was being abusive to him. At this point I have yet to say anything in the chat at all except asking why he keeps diving. Then next 20 lines of chat is him typing out his rage in all chat which I chose to not read. Then the last thing saying I was ranting at him. Seems legit.
