Pretty sure that was just created as an option for unforeseen circumstances. Using racial epithets like nigger, chink, etc (outside of this current descriptive context) would be inappropriate language. You can keep posting shits, fucks, and asses to your heart's content
Also, a note about the points we give for infractions: we don't advertise them 1) because, as Cynthetiq said, we don't want them to be abused, but also 2) because they are merely behind the scenes guidelines for the moderators. Context is important, and moderators are chosen for their judgment. If they feel a certain offense deserves more or fewer points, they are free to make that adjustment, so it would be inappropriate to advertise a set list of points given per type of infraction.
