I know some people have been wishing for a sexual harassment policy.  I have just made such a proposal, titled "Comprehensive harassment and privacy policy", at the Grants:IdeaLab  https://meta.wikimedia.org/wiki/Grants:IdeaLab/Comprehensive_harassment_and_privacy_policy

Suggestions for improvement welcome, or feel free to email me with any private suggestions.
