Comment policies

Sam Ruby has a policy for his blog’s comment section. He edits comments he considers flames with strikethrough and coloring and makes them link to his policy page.
Mark Pilgrim uses a similar policy at his weblog.
Danny Ayers’ policies sort of do the opposite. He boldfaces flames and obscenities because, “[t]hey’re likely to be a lot more entertaining than the usual technical hogwash.”
I wonder if I need a policy here. Nothing interesting ever happens in my comments <snif>.
