It's a procedure for handling harassment. It tells you what to do and what not to do. It's clearly relevant that the procedure was deliberately and knowingly violated.
It's not meaningless, and your example is fairly piss-poor and doesn't relate at all. More importantly, the note was about how it didn't help community, and how PyCon wouldn't take part.
Regardless, I find it ironic that people are publicly shaming a woman for publicly shaming a man.
"PyCon <i>does not condone</i> nor participate in such actions"
You've just used 17 words to characterise a 22 word statement and managed to leave out the part that explicitly condemns the type of behaviour you are defending.
Furthermore, from your own link:
"PyCon values the privacy of all attendees above everything. Except in cases wherein law enforcement must or could be involved, all reports and actions taken are kept confidential by PyCon staff.
Sometimes public shaming is appropriate; sometimes it is not. PyCon seem to me to have concluded that in this woman's case, it was inappropriate. I personally believe that if it prevents this sort of thing in the future, most of the "public shaming" going on is this thread is appropriate and proportionate. Simple. No irony necessary.
Their note about public shaming, while accurate, is just that: a note.
