Let me propose theory as to why women are treated differently on HN, specifically why prominent women have less Karma.
What you are observing is that in many communities, women are not accorded the same celebrity status than men do.
Specific to the US: society tends to idolize men for their work, more so in science and technology, but also in film, music, and television. Women are worshiped for their beauty.
Elon Musk, Steve Jobs, Jack Welsh are pioneers of industry, but women, don't have the same status ascribed to them.
Women pioneers in their field have to be propped up to be used as inspirational role models for girls. Men are naturally propped up by the media.
In communities, Micro celebrities are created. Outside of communities for "traditional" women roles (cooking, being a mom, nutrition), very few, if any, are women.
Ellen Pao, Marisa Mayer, and Elizabeth Holmes have been skewered (for better or worse). In fairness,
In their own communities, and related communities, micro-celebrities gain a natural boost to (karma,reputation,skillpts).
HN, a tech community, tends to idolize pioneers of tech and creators of successful startups.

WRT that throwaway account:
That comment was from 6 years ago. A lot has changed since then.
The owner of that account admitted that she could not attend YC because she does not have impulse control and would cheat on her husband during those 3 months. It's hard for me not to view her perspective through a certain lens--my armchair psyche degree indicates there are issues from her past that cause her to want to sleep with other men the moment her husband is not around. She has found a maladaptive coping mechanism, which is masking the symptom, but not addressing the underlying issues. Similar to how someone with anger issues represses their anger, instead of releasing it (constructively)
Seemingly proving her (and your point) in that same thread, she said being around geeky guys would be like an ethopian being by a buffet. No way that comment would acceptable today.
