You've been around long enough and played on the server enough to have had to pass that MOTD a few dozen times at least. Racism of any form isn't tolerated in TNS, this you should have been more than aware of. I will reduce the ban seeing as no harm was intended and you were immediately apologetic of your actions, don't let it happen again. Last warning.
Micro's Edit: Also, Try to avoid using the word in an appeal, being banned for the word then using it again, isn't the best thing to do.
