@coachm, copyright law is not relevant. I do not know what you mean by the "spirit of copyright law", especially given that modern copyright law derives from the Statute of Queen Ann which was the result of a lobbying campaign by formerly government licensed printers to soften the impact on their cartel by the abolition of censorship laws. Um, that does sound like how things still work!
Can you please tell me of anything Google does that would put you in jail if you did it?
I do not want a web where every statement that someone finds objectionable is removed from the public eye.
