Wrongful banning

So I logged into an infection match in Halo 5. I spawned dead for some reason, only able to spectate the game. While spectating, I got removed from the game for idling (as if I chose to do that). After that I received a ban for not playing the game.
So, 343. Care to explain why I was wrongfully banned?

Please use the ban megathread for any and all ban-related discussion.
