I imagine this would be a non-story if the PyCon Organizers had been directly messaged or contacted and this guy was either asked to leave / reprimanded / asked to apologize. As it stands, the complaint was made via a publicly posted picture on a heavily followed twitter account. Everyone has the right to feel uncomfortable and try to alleviate that discomfort. Knowing of the Code of Conduct, Adria's decision to bring that to the PyCon Organizers attention is certainly a reasonable action. I think your parent comment thinks that regardless of how the PyCon Organizers were notified, they did the right (or at least acceptable thing). The parent comment suggests that they don't agree with Adria's method of contacting the organizers.
