Elmer, I agree with your proposal. Those are common sense rules that can apply for the most basic of conduct. Nobody interested in civil discussion should object to those, as they are quite reasonable. It establishes a line that is not to be crossed, and gives a lot of leeway before that line is reached. You are correct about the "filter" feature being a useful tool to ignore people that do not cross the line, but get close enough to be an annoyance. If more people agree to these terms, I think they should be posted as official rules for the forum, and moderation should avoid confrontation unless these rules are breeched.
