Move the non-security forums off the main page
I think the management should heed the advice than NUMEROUS members suggested... leave some unmoderated forums, but take them off the home page. Put the potentially offensive topics elsewhere on the site with a disclaimer "this is not the opinion of the mangement yadda yadda." Then you can CENSOR THE SECURITY FORUMS ONLY.
I'm suprised the non-security forums haven't been taken off the main page already, considering there were so many people that supported that idea and the anticipated effect that it would create... a more security focused look and feel.
