"AFK" during the zombie round.

Well, my suggestion would be you're only allowed to be AFK if u don't even move;
U just spawn in and u can't move: u move, ur no longer afk.
Also one thing worth mentioning is where do u still consider "spawn" because some people like to hide in assault T room, and call it T spawn.

Exactly, on many maps there are places where you can hide and not be seen, and everyone says I'm AFK in spawn...
