erratic behavior
My online behavior is being monitored (by myself). I have to stop myself from lurking online due to the fact that everybody can see how long I'm on and what I am doing (being online). But what I've done to curb the impression that I am in lurk mode is I sometimes leave myself signed on to a site "accidentally" so that when I am lurking, you can't 'tell if I'm lurking or have just accidentally left a window open.
