"God Mod, AKA Autoing. God-modding is basically being impenetrable and indestructible in every possible way. Don't do this, even if you are roleplaying a God of some sort. Remember: if your character gets killed in a particular storyline, you do not have to declare early retirement and kill off your character completely. Also, autoing is when you try to hit someone and they somehow "always hit without missing." This can also be called character controlling, controlling other characters, etc. It's insulting to the other roleplayer if you suddenly -throw a tomahawk at them with no chance of escaping- because it's pointless."
I'm happy I found this.
