Three existing keywords declined for not meeting guidelines

I would assume it's the use of the actual word that is not really used now.

I think it refers ambiguously to both, and most of the time it would indeed constitute the colloquial word "nigger", not abbreviated/bowdlerized as "n-word". I expressed my view before there should be keywords that provide some context of the usage within the movie, as to whether characters are referring to themselves with it, referring to other characters with it, or uttering the word more generally. I would like assurances that nobody would mistakenly think to apply the "n-word" keyword to a title page for a movie that does not bear any utterance of "nigger" or "n-word", but simply has a performer/character of Black descent present within the movie, and certainly I see that being more of a problem if the keyword was formed from the actual word rather than the abbreviation, but either way, in this day and age, only trolls and bigots (or otherwise children benignly unaware of non-colloquial ways to refer to Black folks) would make that mistake.
