There is a law, that allows "any blog or other website to register a DMCA takedown agent with the U.S. Copyright Office, an obscure bureaucratic prerequisite to enjoying a legal "safe harbor" from copyright lawsuits over third-party posts, such as reader comments." This is a reason why websites like youtube can exist. However, there is a loophole to law. A company based on Las vegas bought copy right for the Las Vegas Review-Journal, just for the purpose of suing any websites who have failed to pay 105 dollars and register with United States Copyright Office.
