Where does it say the sex of the people in the images?

I think it's a weird objection because it's a work of fiction whose content is irrelevant, but the post-revamp screenshot has an email from "Alessandro" but an feminine-looking avatar, and there's the keys for a "Darlene" who looks masculine and a Armando/herman who also looks feminine. Most of us can smell a random record constructor when we're near one but apparently not everyone.
