If someone made a rude comment you can contact admin and there will be repercussions for the offender.
This is absolutely correct. The admins are excellent about letting people know what is and is not appropriate. And, don't worry. You won't get anyone into any trouble that doesn't have it coming. If the modder is a first time offender, he/she will get a slap on the wrist and if she/he has been in trouble before, they'll see a more serious consequence.
