Is playing support Ezreal banable? or even Punishable?

I was and still am under the impression that it is not. I stated "the best support is the support that kills people." in pre game chat and had a well thought out plan. there was a groan in the chat and nothing else till the game loaded in. So the adc afked and I was blamed for him afking. by the rest of the team. THEN when I said no to the surrender vote, I was again threatened of being reported because I was holding the team hostage? both flawless arguments if you ask me. what does the community think? Was it off meta? yes. was it troll and griefing though?
