The node title may be disconcerting, but I don't think it should be deleted. At the very least it's a good reminder not to run obfuscated code, without investigating it first. Its good to be reminded of that occaisionally.... even on linux, a rogue script can do alot of damage to your home directory. What if it modified your ~./bashrc and added kill -1 -1 to it? Alot of people would be stumped and be stuck with a broken system. I shudder to think of what damage could be done to a Microsoft Windows system.
