So, we have all been there before. You are reinforcing a wall and you get team killed for no good reason at all. Maybe you get team killed by accident for drone shooting accidents. Whatever the case may be, you can still report for grieving or cheating/hacking. But, here is one more tip. When the team killing occurs, proceed to follow that team killer through the round and do call outs through the chat to the enemy team on that player. There is nothing more gratifying than watching that person get spanked because of your help to the enemy team. Maybe that will teach them all some manners.
