If club want to affiliate with IPSC, they have to play by the rules and that is what match sanctioning is for. IPSC is one of the most profitable shooting sports for local clubs, so it goes both ways.
In most cases "disruptive or has a penchant for defamatory remarks in regards to the operations of a club" is completely subjective. Personally I haven't said anything here that wasn't true or hasn't happen at the last year match. I was there, so all of that is the first hand experience and I just described how I and other competitors were treated at the match. There are always good and bad things happening at any event and if event organizers are not willing to accept the things for what they are and note them for their future matches, but instead prefer to blame their competitors, because they been doing it like that for 8 years, there is nothing I can do about that.
