If you don't like the rules then make a suggestions thread about it asking for a change and outlining your reasoning. The forums are the place for that kind of discussion, for numerous reasons, chat certainly is not something the staff involved reminded you of.
What you don't do, is violate our chat rules and cause arguments in chat. That isn't a civilized discussion that's you trolling and breaking our rules. Which as you discovered leads to a ban.

Now if you have an actual complaint about the rules you can make a thread in the suggestions section and I will happily debate the merits of the no swearing rule with you.

However given your complete disregard for the chat rules you will be unbanned in 72hours from this post, I suggest you take this time to reflect upon the rules. Especially the one that states "listen to staff".
If you have a problem with the decision of a staff member raise it with them in PM or on the forums.
