In the martial arts businesses, there is a group of gangland rogue business owners who use misinformation and regurgitated rumoring lies to perpetuate schemes upon the competitors of the martial arts business.  So much that they challenge each other for a vindication match which never happens.  Just phone calls to the police and false police reports turning into lawsuits literally.  Sounds crazy, these affairs are an ongoing activity behind the scenes of the mixed martial arts net workings.
