Something for Perl event organisers to take into consideration
I’ve decided this is so important to me that I’ll no longer attend or speak at conferences that don’t adopt and publish a code of conduct. I’ll also be using whatever clout I’ve got to encourage conference organizers to adopt and publish anti-harassment policies. […] So why, given the issues [with codes of conduct that] I outlined above, do I take this so seriously?
He makes the point, but does not emphasise it enough in my opinion: the code of conduct is not there to communicate to attendants how or how not to behave (in which capacity it is superfluous with the well-behaved majority and ineffective with perpetrators): it is there to reassure members of minorities that they will be heard and their concerns are understood.
