looking for an attorney familiar with defamation/libel claims. Need to do a legal research regarding anonymously posted defamatory content on YouTube against our client. The request to remove content was sent to YouTube, YouTube refused to remove the content based on the fact that they don't check its veracity and suggested we sue the people who posted this content directly. The problem is the content was posted anonymously. Need to find laws and regulations, which could mandate YouTube to remove anonymously posted content or, if such do not exist, research what recourse the client may have (whether he can file a complaint against Google with the court and on what basis or any other legal measures he may implement).
