I'm Brazilian and that is really not true. Orkut is here what Facebook is at the U.S., it's "the" social networking site. Almost everyone with Internet access have a orkut. And as a mainstream communication tool, many people use it to offend, scam, spread fud, and all sorts of bad things.
Here, if you are being damaged by offending posts, anonymous or not, you can get help from the police. And if it's a anonymous post that couldn't be tracked, who's to blame? Apparently the judge understood (and I do too) that Google is to blame because it created that communication medium. If Google made it anonymous, it took the risk this medium would be used to this sort of (illegal) thing. Something like "if it wasn't for Google creating this orkut thing, this would never have happened... and someone needs to be held responsible for this."
Yeah, we believe in freedom of expression on the Internet. But "your freedom ends where the next one's start". This freedom do not gives you the right to offend others. You have the freedom to say whatever you want, as long as you don't use this freedom to clearly offend someone.
