Hey Grape, welcome to the forums. Nice to see you around here. As many members and admins said above: Children are allowed and it is not in our hand to control them. If their parents allow them to play games which are rated 18+... There is nothing any admin can do against this kids. Sure, they could ban them,
but why? For playing a game? IMHO there are only two reasons: they are disrespectful or offensive to other players.
Also you can not expect from all players to change their gaming style or terms. We have junior members like Rascal, Cobrabites Jr and many more. And playing with them is always fun. See you on the field
