That's the problem, no one in their right mind would do that. It should be more along the lines of "rumor has it Jim curses like a peasant".
Suppose a letter has marching orders for an army, but also some curses in it. If anyone flags it the opposing army could receive marching orders. Huge flaw. I suggest either make the knowledge of the curses IC but the details of the letter OOC or rework the feature to prevent this from happening (like restrict peer review only to people who could see the original letter, or let the person flagging select who they want to review it).
