Anti-harassment is a big topic in regards to technology conferences and events today. While most organizers would agree that harassment is a bad thing the issue comes as to how to define it and then what to do about it when it happens. Having written anti-harassment guidelines makes dealing with issues far easier.
The Geek Feminism Wiki has a fill in the blank Anti-Harassment Policy for events that seems pretty straight forward. The Policy has been released under Creative Commons Zero license so if you want to add or subtract from it’s wording you can do so freely.
I have found when helping run events that it’s better to have rules and not need them, than not have rules and need them. Having policies written in black and white makes dealing with troublesome people a thousand times easier. Additionally in todays world of hyper vigilance when it comes to political correctness taking a few minutes to customize an anti-harassment policy for your event shows attendees and sponsors that you’ve taken the effort to deal with this issue even if deep down you really don’t care.
