DNR - Do not revive.
Simply a tab in OOC preferences that makes you be unable to be scanned by cloning scanners, (Mental interface failure, everytime) unable to be cloned, (Could make "Clone" button greyed out in cloning records) unable to be defibbed, (Gives a failure message) unable to be strange reagent-ed, (Just gibs?) and unborgable. (Brain loses spark?)
tl;dr you lazy asshole, this isn't only a sentence add an option for people that get killed by, for example, a traitor or their own stupidity and don't want to return for reasons. (AFK, deciding to become an observer, blah.)
