Yes, one of the posters here has pointed out that Brazil forbids anonymous speech, which I was not aware of when I made the submission*. However, Orkut requires you to sign in - unless there's some "anonymous coward" option I missed - so the poster must have supplied an email address that the Brazilian authorities could not or did not trace. How is that Google's fault? There are no magic wands, and this is still a blatant case of "shoot the messenger".
And regarding the Italian case, they didn't just fine Google, they convicted four Google employees - the second article I linked to goes into some detail, includes personal statements from two of those convicted, and also has this comment from a Google VP: "To be clear, none of the four Googlers charged had anything to do with this video. They did not appear in it, film it, upload it or review it. None of them know the people involved or were even aware of the video's existence until after it was removed." That's not just shooting the messenger, that's shooting the messenger's family and neighbours.
*(how does that even work?! do they fine the telephone company whenever somebody makes an anonymous call? do they arrest the owners of walls whenever somebody paints graffiti? it is like forbidding the tide from coming in or the sun from rising in the morning)
