"AFK" during the zombie round.

Hi, I think it would be a good idea to do something about players who go "afk" during the zombie round and try to find places in the bases where they won't get shot, but during the ct round they are no longer "afk". Personally, I often see this from both casual players and players with admin/s.admin privileges. Given that there are no rules regarding this situation, players are abusing these actions. So I think it would be a good idea to do something about such players, to impose some kind of punishment or something else.
