My very simple rules for commenting on Behind the Black have now been added to the right column (seen at the bottom of the page on mobile devices), placed just above the box listing the last ten comments. The rules are hardly odious:
I welcome all opinions, even those that strongly criticize my commentary.
However, name-calling and obscenities will not be tolerated. First time offenders who are new to the site will be warned. Second time offenders or first time offenders who have been here awhile will be suspended for a week. After that, I will ban you. Period.
I have stated these rules in posts in the past. Now they are permanently displayed at a place where I think all commenters will see them. There will therefore be no excuse for violating them in the future.
