"People who flock to fantasy conventions and signings make up an 'inherently vulnerable community'...."

"... They 'wrap themselves around a beloved text so it becomes their self-identity'.... They want to share their souls with the creators of these works. 'And if you have morality around it, you say "no."'... [I]n my conversations with Gaiman’s old friends, collaborators, and peers, nearly all of them told me that they never imagined that Gaiman’s affairs could have been anything but enthusiastically consensual. As one prominent editor in the field puts it, 'The one thing I hear again and again, largely from women, is "He was always nice to me. He was always a gentleman."' The writer Kelly Link, who met Gaiman at a reading in 1997, recalls finding him charmingly goofy. 'He was hapless in a way that was kind of exasperating,' she says, 'but also made him seem very harmless.' Someone who had a sexual relationship with Gaiman in the aughts recalls him flipping through questions fans wrote on cards at a Q&A session. Once, a fan asked if she could be his 'sex slave': 'He read it aloud and said, "Well, no." He’d be very demure.' But there were some who saw another side of the author....."

From "There Is No Safe Word/How the best-selling fantasy author Neil Gaiman hid the darkest parts of himself for decades" (New York Magazine).

That's a long article, and you are probably blocked by the paywall.  Here's Gaiman's answer (on his website). Here's the NYT article about it, "Neil Gaiman Responds to Explosive Report of Sexual Assault/'I have never engaged in non-consensual sexual activity with anyone,' said the best-selling author in response to allegations in New York magazine":

Katherine Kendall, 36, was one of the women interviewed by Lila Shapiro for the New York magazine story.... In an interview with The Times, Kendall described the “culture of secrecy” around Gaiman. “Neil’s works were his bait, and promotional events were his hunting ground,” she said. “As long as his publishers and professional collaborators remain silent, Neil will continue to have unrestricted access to vulnerable women.”

From Gaiman's statement:

I went back to read the messages I exchanged with the women... These messages read now as they did when I received them – of two people enjoying entirely consensual sexual relationships and wanting to see one another again.... And I also realise, looking through them, years later, that I could have and should have done so much better. I was emotionally unavailable while being sexually available, self-focused and not as thoughtful as I could or should have been....

Like most of us, I’m learning, and I'm trying to do the work needed....

Do the work! I don't think the kind of people who have popularized the phrase "do the work" will accept this kind of bailing out:

At the same time, as I reflect on my past – and as I re-review everything that actually happened as opposed to what is being alleged – I don't accept there was any abuse. To repeat, I have never engaged in non-consensual sexual activity with anyone.

He's trying to preserve his literary career and fend off lawsuits. He's willing to say he'll "do the work" with respect to becoming a better person going forward, but when it comes to the past, he wants to be accepted as merely a jerk and never a rapist.
