People always whine about how strict the chat rules are in this game and I'll never understand it. I've played for the entire duration of ARR and never once even received a warning. I've gotten into some major arguments, too.

If you're getting penalized or are afraid you will if you say anything, that's a you problem. If you'll get in trouble for speaking how you usually do, that means you're probably being an ass. Consider the language you use.
