The Zen of Anonymity

Given: Some graffiti is on the wall. Question: who is `responsible' or `liable' for graffiti?

This question already has a known answer. The author of the words is the one that is liable for them. No other parties are liable unless they had prior knowledge; this would make them conspirators. In libel cases specifically, if you can prove who the author was, you can sue. If you can't, too bad. Heh, heh, heh. I asked Mike Godwin about this specifically a few months ago. I mention him here to give him to opportunity to correct or elaborate. Eric
