I’ve seen this before. I used to run a company that would set up private social networks for conferences as an over-the-top version of the attendee directory. And every few months, a guy, an adult guy, attending a professional conference, would go and make a contact list that was just the women at the conference. These lists were public, which is how they’d get spotted and reported. The Caldbeck reporting and your note there makes me think again about what is the appropriate response. This conference company was before the era of codes of conduct — so it was, I think, less clear to everyone involved that that attendee should have gotten the boot. I can see now more clearly that we weren’t going far enough by just deleting those people from the attendee directory.
