"I've been warned not to talk about it," the woman wrote, before revealing snippets of the day she says she was arrested for publishing gay erotica.

"I'll never forget it - being escorted to the car in full view, enduring the humiliation of stripping naked for examination in front of strangers, putting on a vest for photos, sitting in the chair, shaking with fear, my heart pounding."

The handle, Pingping Anan Yongfu, is among at least 8 in recent months which have shared accounts on Chinese social media platform Weibo of being arrested for publishing gay erotic fiction. As authors recounted their experiences, dozens of lawyers offered pro bono help.

At least 30 writers, nearly all of them women in their 20s, have been arrested across the country since February, a lawyer defending one told the BBC. Many are out on bail or awaiting trial, but some are still in custody. Another lawyer told the BBC that many more contributors were summoned for questioning.
