First: some people pretent that they are newbie and need help with the game while they are actually antag and when your busy helping them they kill you. This is a real dick and OOC move. Make a rule for this (not all help requests. Like when someone asks you that they are doing their job but it doesn’t work right and ask for your help. This one is way more realistic)
Second:some HoP (or anyone with access) name themselves like antags (sithlord ,head of death,etc) while this is not a problem for most players, newbies may be having problem with this and actually robust and space some dude because he looked like an antag. This should be controlled on LRP server where there are more newbies.
