Maybe to make it fair, both you and the opponent have to approve of banning a spectator. Like a little message in the chat bar would appear like: fryfrey would like to ban (spectator name) from this battle. Do you agree? Yes No. And the command could be /banspectator (spectator name) to avoid confusion between spectator banning and regular banning. I do know this idea has been pitched a few times, but if it is fair to everyone, it can do well.
Just to say there is a "/ignore insert-name-here" command for this.
Also you can always pm a moderator for particularly troublesome users
