This is another thing that lands on these threads, like clockwork: one time, a woman freaked out over an overheard joke, complained publicly on Twitter, ended up getting someone fired, and was then fired herself. "And you are lynching the negroes."

That this has nothing whatsoever to do with the comment thread we're on about someone's daughter being called a prostitute at DEFCON is unimportant; what's important is to deploy as many countermeasures as possible to prevent sincere conversation about harassment.
