You can top players with lousy ethics playing without letting off a warning despite making noise during competition. Becoming a nuisance is one thing, disrupting other players during a 'fair' competition is worst. What's more, is the last match a real chess?
Referee should take a serious stand on this except such games are subjected to strong scrutiny of the public. The image of SCXQ is at stake if such bad practises are condoned.
