As I remember,when I used to play ZB,lots of people did /kill so it's not a big deal if you do /kill,wait a few seconds and /kill,disconnecting& alias& reconnecting may get you penalized for reconnecting for 60 seconds or so,you may not forget that on the one hand people usually know that it's you when you reconnect and on the other hand it's enough time to a hacker to run away with out being caught.
