Links to your site

One of the more interesting reactions to the new copyright laws in Australia is on links and law, titled "How to stop links to your site".
There is a whole page on how to avoid being "framed", as if that were a real concern. What their on about is best demonstrated by choosing a link from any article on About.com. The page will appear under a wide About.com banner. About.com uses invasive Javascript to inject the code for their banner into the new page if it won't open in the frame.
It's not hard to overcome such programming. Just right-click anywhere in the new page and choose 'Open in new window' (or 'Open in new frame' if you're using Firefox.)

There is code that can be inserted into a web document to prevent being "framed"; and code that can prevent injected Javascript.

Thing is, this is the Internet. The whole idea of the Net is to get links to your site, blog, or page.

Not being "framed" has little or nothing to do with the dangers of the new copyright law, whether you have links to offending material or not. Your code may prevent someone from using a link to your page, but that doesn't mean they won't be able to copy the link and use it in a new browser window.
All the code does is force your page into a new window.

If the idea is to protect yourself from being visible to Australians, you've failed.
There is better technology for that on every server. Just set the server exclusions to Australian IP addresses. Not only will your site not be "framed" and exposed to Australia's restrictive laws, but it will not appear at all. You just redirect the user to a customized error page to explain.

Some servers will allow you to do this on a page by page basis, leaving parts of your site available while any offensive material is blocked. If the server doesn't have this facility (or you don't have access to it), there are Python and Perl scripts that can be employed.
This sort of scripting can be used on blogs, too.
Savvy webmasters will redirect the visitor to a customized error page for a few seconds, then back to the main page for the site. There's no sense in losing a visitor.
