Can you get banned for helping the team? (not feeding)

Like this lux was like "Im too good for this team" and "this game is too easy" , so she stooped doing objective unless if u call killing enemies that want to kill you objective, and she started helping the enemy team by telling them what to do, like "rush towers and you guys will win trust me" and stuff like that, im just wondering is this something you can get punished for?
