I applaud the PyCon organizers for clearly delineating what is acceptable behavior and what is not. I especially applaud them for including public shaming in the "unacceptable" category.

The rest of their code is there to protect conference goers. The sections discussing harassment are there for a reason - harassment is a real problem at these events.

Similarly, conference goers should be protected from the threat of being publicized as a less-than-human creature on the Internet. There's been some discussion of the reaction to Adria and Jesse. There could just as likely have been a strong, dangerous reaction to the men who made the comments. Saying "these guys are a threat to women" on the Internet could actually put them in danger, and no one should expect to be put in that situation by attending PyCon.
