So even if you're not actively harassing a particular player, they are still considered prohibited.
Within the context of harassment, as they're expanded in that section of the Terms. Also, note that the operative term "could" does not mean that they do in all cases (though I would argue that discriminatory statements certainly do fall under a "would"). This places this under their discretion for enforcement.

EDIT: Before you claim that this is a defense of explicit advertisements, don't. As the saying goes, there's a time and a place, and that sort of ad certainly doesn't belong in a public search index.
