There is a problem with this solution–a legal problem. Your web page is covered by copyright, which gives you the right to forbid other people from making either copies or derivative works. A browser that displays your page as you intended is making a copy, but one to which you have given implicit authorization by putting your page on the web. A browser that displays your page with back links added is creating a derivative work–one that you may not have intended and, arguably, did not authorize. To make sure your lies cannot be answered, you notify Netscape that they are not authorized to display your page with back links added.
