What am I confused about?

Well I'm confused about the chat rule about no cussing and young childeren. There is no rule against being underaged andonline, but people do it anyways. In our chat rules, it says nothing about being punished for being underaged, yet people still get banned for it.

If they get banned for being underaged, why in the chat do we have rules such as the "No cussing allowed" because there are young kids on the chat. But if young kids are banned for being underaged, what is the meaning of this rule?

Also If young are banned, don't we need to put tha as a rule in out chat room rules?

I hope this offends on one.
