How is this bannable

came back from a 2 week suspension today and the very first game was a group that was partied up and I was odd man out, if you could see what they was saying you could see it was a lot worse then this. I ended up having to play jhinn top cause I had no top and was getting rekt from amu top and they thought I was feeding on purpose.
