The most powerful action that could be taken is for actual fighters to boycott the WBA and refuse to fight for any of it's belts or any of it's bouts... If you are fighting in an association where you train and fight your guts out, and clearly win a fight, but aren't gaurantee'd victory based on poor judging, then that should be reason enough to refuse to fight under that association...

If I was a fighter I would really have a problem with it..
