I agree. Not knocking the lads efforts, but is this really the sort of thing a twelve year old should be doing? I don't think I'd want my youngest who are almost 14, moderating adults. So he is the one who is going to be in control of moderating any bad language, racism etc? Even some jokes aren't suitable for a twelve year old - even the ones on this forum!
I wouldn't even recommend that he keeps it just for kids, there are enough ways for pervs to contact children on the net without this.
I don't think his parents have thought this through properly, I really don't. :
