Id like to add that you SHOULD be immune to player attacks while afk. I think it would lead to \"afk farming\", where thief character(usually) or some other says to themselves, \"AFK! That means an easy target!\" You come back from whatever to find your character dead, and with no items, basically, just like when character was started, except for skills/lvl. Not that people would JUST look for afks, but if they saw them, its \"got killed/looted\" message for the afk player...
