While I was playing a "Insanity" server I stood at one point of the map sniping people, and apparently I actually stood there too long and was kicked out of the server after awhile despite actively firing my weapon. I wasn't being targeted by anyone else and the nest I was in gave good coverage so I never needed to move.
I know some people would consider standing in one spot and shooting things a rather unsavory way of playing games, but I think being kicked for camping is a bit too much. I was still firing and taking out enemies after all. It was hard for me to notice the "You're about to be kicked for idling" message in the chat box amidst all the kill messages, film grain and rather tiny text until I was actually kicked.
Perhaps consider having the idle kicker account for players that are still firing their gun and/or consider making the Text Message Warning bigger and more noticeable.
