I tend to boycott matches by just not attending. If enough people do the same and the turnout for the match is so low that they eventually just quit having them then I win. Conversely, if a match is popular and attendance is high it will likely thrive and grow.

I imagine if a club is putting on matches nobody wants then eventually they won't be putting on the matches. Also, if popular matches are pushed out of a club or discontinued for whatever reason, those matches will likely resurface elsewhere taking their enthusiastic shooters with them to greener pastures.

Eventually, everything will sort itself out.

The worst thing is if shooters continue to shoot poorly run, half ass matches because they feel that is their only option. People will continue to show up and the matches will carry on as they are and nothing will change.
