Remove the Tribunal warning.
I know for a fact my cousin who just started playing has said nothing in chat. He spent the entire match talking to us in the room with him and didn't type anything. After about three matches he got the "tribunal warning" saying his fellow teammates reported him.
It's been hard enough to get this guy to play the game and now this happens. You want to give players the ability to report people for nothing, fine, but giving a person a "tribunal warning" is not only not needed, it's counter to the idea of what the report system is supposed to represent.
Again, three of us were watching him play three matches where he said nothing. Not hello, not GLHF, nothing. Not a word. The reports were obviously from people making false reports and probably to the entire team. When the message popped up we were talking about how to build items and explaining the shop to him. We SIMULTANEOUSLY yelled out "WTF" !?
Remove the "warning" when other players report you. There is no way for the system to know if it's due to false reports, so it's completely unnecessary and needs to go away. It's a huge turnoff to new players who have done nothing wrong. The kind of players this game NEEDS.
