There is a question to be asked of where does one draw the line about policing stuff that happens in virtual reality. Are we to start prosecuting people for espionage and insider trading in Eve Online too? Can we punish the church because God isn't answering my prayers in a timely manner?
(I don't think regulation is the answer. They had their 15 minutes of fame; it's time for everybody to form a new clique and cut Google out of it-- just like the Twitter exodus.)
