What about 'wreckers'?

Live Stewards are used to monitor the majority of our events to prevent immature and unsportsmanlike conduct on our servers. Blatant disrespect or disregard for the rights of fellow racers will be dealt with promptly and subject to harsh penalties, including the possible loss of Race2Play membership. (This does not mean we will be in the business to police racing incidents and mistakes, which are honest circumstances of every form of racing at every level.)
