That headline is giving them too much credit. They merely let kids fight and essentially yelled "CRIPPLE FIGHT! KICK HIM IN THE BALLS!" like Cartman would instead of stopping it when they saw it.
A "ringleader of a child fight club" would need to organize fights and betting, make sure everyone keeps their mouth shut. You know, the basics. You gotta train your champs a bit so you get a good show going. I'm not saying I'm sad about it but as far as child fight clubs go they didn't really have anything going. If there was a child fight club union they wouldn't qualify is all I'm saying.
Seriously though fuck those kinds of people.
