Who would use copyright as an excuse for censorship? Oh, you know...everybody.
As an aside on this article about a Brazilian teenager auctioning off her virginity, the article mentions that the YouTube video was removed dude to "due to multiple third-party notifications of copyright infringement".
So...someone already copyrighted her video to auction off her virginity? Dirty pirate!
Obviously, someone was offended--and used copyright to censor her video.
And that is why letting people pull stuff off the internet due to copyright is bad.
