in regards to SFC and Melbourne Heart, these are incidents that are not related. firstly in regards to Heart, it was 1 fan who was caught and prosecuted under the law and given a 5 year ban. in Sydney's case There was no large press covering of the incident and according to police reports he was not connected to the club (whether true or not).
Vic V WSW was an all out internet fap fest, a clearly pre organised confrontation and retaliation plastered all over social media and then there was the continued behaviour in the stadium that followed by WSW supports. The Fact that it appears that Northgate are running RBB now should be the larger concern for everyone.
I don' think this is the right avenue to take, I think locking out Active supporters is a better way of dealing with these issues. If they are the problem then they need to accept the blame. imaging a Sydney Derby with no RBB?
