Need a sense of security for game creators
      

  I'd like to hear some ways you could abuse/grief in a multiplayer Diablo III game.I'm not saying there's no plausible way to do it, there's always a way to grief, I'm just curious.And let's exclude completely unknown variables like a hack or cheat.
