Not entering into any debates, and unless instructed differently from the site owner the following will come into effect immediately
The "N" word and any and ALL variations on spelling and pronunciation will be considered to be a racist remark and will be dealt with under the current guidelines for bigotry and racism.
Edit: Context is to be considered. However, using it to call someone or a group of people a name, even if as a joke is not acceptable.
It has been mentioned to me that the word is used in many song lyrics, most sung by those who are most offended by the word, when they mention it, it is not racist or bigoted.
Fair play
If you think it may be considered bigoted or racist, then please do not use it, find another word or better still do not post that sentence
Thank you
