I think there should be a mod that makes players invincible(unkillable) when they start typing and stop being invincible when they stop typing. And when they have not moved, shot, typed, activated something, jetted, or did an emote for more than 2 minutes they will get invincibility and will lose it when they move or do something to tell the server they aren't AFK. Long story short, a mod that gives players invincibility when they are typing or AFK for more than 2 minutes. So you won't get killed by zombies/players in deathmatch servers when you type or go afk. I think this would be possible cause there is already a non-combatant player type that makes it so you cant be hurt by players. All you need is a way to make typing and not moving at all for 2 minutes to toggle you to become the playertype and then something to change back to whatever playertype you were before. I think it sounds pretty simple, but I don't know scripting.
