One more quote. Three years ago, Charlotte Alter investigated sexual harassment in the Effective Altruism movement (a movent which formed around Yudkowsky's mailing lists and blogs) for Time magazine.

This story is based on interviews with more than 30 current and former effective altruists and people who live among them. Many of the women spoke on condition of anonymity to avoid personal or professional reprisals, ... Their accounts were corroborated by other parties to the incidents, by people to whom the women spoke shortly afterward, and by contemporaneous documents and screenshots. While a few women have raised these issues on online forums, many spoke to TIME about their experiences with sexual misconduct in EA communities for the first time.

One recalled being “groomed” by a powerful man nearly twice her age who argued that “pedophilic relationships” were both perfectly natural and highly educational. Another told TIME a much older EA recruited her to join his polyamorous relationship while she was still in college. A third described an unsettling experience with an influential figure in EA whose role included picking out promising students and funneling them towards highly coveted jobs. After that leader arranged for her to be flown to the U.K. for a job interview, she recalls being surprised to discover that she was expected to stay in his home, not a hotel. When she arrived, she says, “he told me he needed to masturbate before seeing me.”

A necessary but not sufficient response to stories like that is to make it utterly clear that this kind of behavior is not tolerated in your community and that you will take complaints of sexual harassment very seriously. Three years later, Yudkowsky is still blathering about how statutory rape is not always wrong and its important not to move too quickly to judgement.

Edit: See also this response by a professor who was asked why he had asked Epstein to fund a 2016 conference on sexual consent and campus rape.

I was not then and am not now aware of any evidence that Jeffrey Epstein was a ‘pedophile’ in the technical sense; his sexual preference appears to have been for young women aged 16-22, which would at most reflect partial ephebophilia. Although most of the women who were involved with him at that age retrospectively regret it, I am unaware of any evidence that the contacts were non-consensual at the time. (it goes on. I do not advise reading further but I note that Epstein's known victims were as young as 14)

The professor left Austin TX on retirement and now lives in California.
