Does No Copyright Mean I Can Use It?

Any content someone creates is protected by international copyright law, meaning you can't re-post or re-use it without the owner's explicit permission. The fact that the owner put it online does not imply permission that you can re-use it, and if you re-use content without permission you are breaking the law.
