If you click on a link and find yourself at an unexpected website, you may have been ‘pagejacked’. This happens when someone steals part of a real website and uses it in a fake site. If they use enough of the real site, Internet search engines can be tricked into listing the fake site and people will visit it accidentally. The fake site could contain unwanted or offensive material. As an online merchant trading via a website, you need to know that your site isn’t being stolen in this way. Unfortunately you can’t prevent pagejacking; you can only deal with it after you know it’s a problem.

In jacking, you take control of another webmasters page and redirect it for your own means. Its not just stealing information. From what I have read, it is actually a type of fraud, and considered against the law, which means you could have some nasty consequences if you are involved in it.
