What could be done to increase the number of active contributors to the projects?

As I was reviewing some of the reasons why people were posting threads at WR (the site which may not be named...), I noticed a few cases where admins had called contributors really nasty names. Not your typical nastiness but over-the-top nastiness. They were reported, and not desysopped. I find that disturbing. Would there be support for a "Ten Words that will get you auto-de-sysopped" list ? Like the F-bomb for instance.
