I do ninja "User CP" checks*, just in case people happen to glance at "Who's Online" and catch me looking. Coz, you know, they might think I care about reputation. Which I don't (of course). I am above such considerations. Really.
Of course, when I catch other people looking at their "User CP", I smirk knowingly and consider telling them they will go blind.
*ninja "User CP" check: checking the "User CP" and then immediately performing a "New Posts" search in a new tab.
