Rather than worrying about the effects of shaming people publicly, conferences are basically putting up "no glass in pool area" and announcing their triumph at conquering this problem.
As I recall it, by the end of everything, the jokesters had been asked to leave the conference and subsequently lost their jobs, and the community blowback after that resulted in the originally offended person also losing her job because the controversy would have made it basically impossible for her to act as a developer community liason.
There were no winners, but PyCon apparently does now make procedures for handling sexual harassment, etc. much more clear in conference materials.
edit: though clearly my recollection was flawed in some ways - among other things, only 2 lost jobs and I was incorrect about them being asked to leave the conference.
I can in no way speak for anyone's employer, but it's worth noting that only one of the individuals lost their job.
I currently serve as the co-chair for the PyCon Program Committee, and as a director of the Python Software Foundation.
Thanks for what you do for Python.
