Kids on adult shoes/ why they dont belong there ?

Recent events have now highlighted this problem.
IMO, This is just bad promoting.
Kids matches belong on separate events. And intelligent adults know this.
They usually appear on adult bills only to pad out the card as the promoter doesnt have the fighters/contacts to put on a proper adult show. Or knows these kids are bringing a load of family members and can sell a few tickets for them.
Meanwhile the rest of the crowd who have come to see some real fights complain and go to the bar.(and you lose some future punters,as people dont like being ripped off)
Also the worst behavior i see at shows is usually from the fighters family members. And this triples if it's a junior and you add alcohol !
Kids belong on separate events,period !

I totally agree that the rules etc were fine.Basically a grappling/no gi jiu jitsu match.
Had this happened on a mat in a amateur daytime event know one would have batted an eyelid. Which is exactly why that's where kids matches should take place until at least 14 imo.(as far as mma goes)
As for Thai n KB. Just use a sanctioning body/association whos rules follow ABAE guidelines as near as possible, and at least when you end up in court you have something official to fall back on.
