If, say, the guy had made mods smirking at the George Floyd protests, had made skin-color mods, and had also said "no comment" when asked what the 'n' and 'c' tags represented, would you still go with your first assumption?
That he's clearly more than a little racist isn't enough for me to defend nuking the guy's account without warning or explanation. But it is enough to make me think twice about blindly downloading and running the guy's code (which also downloads a lot of stuff/self-updates).
Who knows what other norms of basic decency this anonymous person from 4chan would violate.
So I loaded up A111, selected the 'n' category, and ran a few pictures using random artists from said category.
The results were all black. The category itself is actually useful to me, now that I know it exists — I use the AI to generate illustrations for my fanfiction, and getting non-white, non-asian outputs is difficult at best — but labelling it "n" is, uh, suspicious.
In combination with everything else, I don't think there's really any doubts about his thought process here. :(
My first assumption on encountering a table field with a standalone "n" would be that it's an abbreviation of "no". So I'm surprised people are assuming so strongly here that this is instead code for a racist word. This is quite a harsh accusation, given the lack of evidence.
It will be quite embarrassing all round if this just turns out to be a run-of-the-mill copyright strike, or similar.
