While I was playing today I ran into a hacker and since there was a staff member in my game, he quickly banned the player. When the player was banned, I realized no one but the staff member knew the player had been cheating/banned, unlike a sentinel ban where all players in the lobby get a message in chat. My suggestion is this: if a player gets banned by a staff member in-game, display a message in chat detailing who got banned and for what (you can also add which staff member banned them). I know it's a pretty simple suggestion that doesn't matter that much, but I still think it'd be a nice addition.
