This issue arose again recently. I thought most people had more sense than to blindly copy things from one web site and then post those things on another web site. I was wrong.
Copyright laws DO apply to almost everything published on the World Wide Web. There are strong penalties for violating copyrights.
I believe that the copyright statement of the Privacy Blog is much more liberal than that found on most other web sites. Still, you cannot legally copy lots of articles from this blog and then post them elsewhere without permission. However, you may legally copy and republish an occasional article or two for non-commercial purposes.
