Make the rules simple enough that anyone can remember them after one read, then post violating messages on a new board called "Rogue's Gallery" along with how they were resolved, e.g. Mod deleted the post, Mod removed offending language, User was asked to modify the post, User was suspended for egregious violation, User was banned for repeated egregious violations, etc. That way people can objectively see what the boundaries are. Simplicity and clarity.
