Well, if someone is just going out and saying "WELL DERP, YOU HAVE LOW KARMA SO I'M JUST GOING AHEAD AND KILLING YOU SINCE YOU COULDDD BE A TRAITOR AND I WON'T LOSE MUCH KARMA IF I DON'T. DERPDERP." I don't think it should be allowed. I should know because I used to do this and it was a MAJOR asshat move when people lose their T rounds or just get killed all the time because of PERHAPS an accident occurring and they lost all their karma.
Also, Apie, no offense but I can't understand HALF of the stuff you type. Could you perhaps type a little more clearly?..
