Yes. Copyright attaches to original creative work. It is not something that you must register, but rather it is automatically created at the time that the work is authored. It is not necessary for the author to state that the work is subject to copyright for the copyright to exist. There might be some argument that the owner of the copyright impliedly granted a licence for use (e.g. posting script or code in a programming forum) but in other cases the retention of the copyright might be imperative to the owner (e.g. posting a story idea in a writing forum). Overall, you should act as if the work is copyrighted and give credit if you intend to quote or use the content.
