Heavier fines need to be handed down, plus points deduction, for the side fans thatare responsible.
However I am not in Favour of this unless it could be proved conclusively that the fans are identified as that of the punished club.
also I am not in favour of the Referee in abandoning matches, where the fans may use this ploy if they are losing at the time or the match is simply awarded to the team at which the fans are directing the racist chants to, but again it would have to be conclusive evidence.
in respect where the matches involve the rags, its OK, as the are beyond any rules, because they appear to be able to change them at a moments notice.
