Earlier quoted context omitted.
There is a lot of DM spam on Twitter, TikTok, and Facebook/Instagram/Whatsapp involving explicit photos of female genitalia that would meet the criteria of obscene material under California's law[1] around sending unsolicited images by electronic means (SB 53). 1. https://leginfo.legislature.ca.gov/faces/billTextClient.xhtm...
Are they sent by the women who own the genitalia? I have never once received an unwanted nude from a woman but as spam whereas with men it has happened enough times for me to believe without statistical justification that unwanted images of male genitalia would be more common.
I am not sure how this is relevant to building a classifier, however. Or relevant to California law.
