Fat, skinny, tall, short, bald, or horse-faced are descriptions, not judgments. If someone is skinny, they know they're skinny [insert anything else in there]. Some MSCs show "apparent race". Again, it's not a judgment or an insult to report someone as Pacific Islander when they're Asian - it's a description that sets Filipino Benny apart from Caucasian Benny.
I would leave at most the first letter intact. If the word can be figured out from context I might even censor the whole thing as in "**** a duck" or, to quote the president, "son of a *****".
It might not be an insult, but it would still be a judgment.
So I just did a shop that required restroom pics. In one of the men's room stalls was graffiti that said "FECK ME" and then underneath that. someone else had graffiti'd "six times". The vandalism had then been scratched over, but were both still legible. I took a pic of that and submitted it. Shop company didn't say a word about it.
