You're barking up the wrong tree. mIRC isn't managing chat rooms, mIRC is just used to connect to them. It's like yelling at your TV because of what's broadcasted, it's just futile.

Also, "age play" does not involve the abuse of children, and it's not the role of you, me, the mIRC board or the US government to regulate it. Child pornography is already illegal in most countries that host IRC servers.
