I can honestly say that I am friendly. I trust players, which often gets me killed. However, if you piss me off or are a bandit, then you had better watch out, cuz there aint no saving you. I stabbed a man to death with a bloody screwdriver once cuz he called my character a n*gger. I also shot many bandits to death who were camping waiting for innocent players. The truth is there's no real "friendly" players unless you actually know them. You can never really be sure about anyone, but if someone comes up behind you and yells friendly, then you can probably trust them. Just don't attack or provoke friendly players, cuz even they can kill you if pissed off.
