Say you've written an article that's getting a lot of attention. Say that someone running a blog on blogspot.com has copied the content of your article, word for word, posting it on their blog. It's a case of outright theft of your work. Maybe you spent the weekend traveling and staying in a hotel to get the information for that article, and they're directly stealing your hard work. It's a case of copyright infringement and obviously going to violate the terms of service for blogspot.com Who do you call?
