I don't specifically seek out raceplay vids but I am surprised when the extreme type is said when not expected
Aidra Fox and Blair Williams are two examples I can think of saying the n-word.
Brooklyn Chase never said the n-word but she wrote it on a sign for her 1st Interracial Blowbang scene. I suspect that photo is why the scene was removed from the DFXtra site after Gamma became the new owner (lots of woke executives)
Majority of performers and fans don't think words like "BBC", "Big Black Cock", "White Pussy" are offensive but some do and the minority are usually very vocal and will lecture about how it's bad, etc
I don't think the n-word is ever coming back to professional porn except to places like Dick Drainers and Black Payback but more sites seem to be comfortable saying BBC again after refraining from saying it for several years (2020-2023)
I've bought some voice notes from pornstars I like. Almost all are comfortable saying BBC. Other people I spoke to who buy custom vids have said the same. For the right price and (mostly) private they will do some raceplay for amateur/self made content. Virtue signaling is fake
