Automating defenses

It would not be difficult to provide plugins for email client programs to search and destroy double URL links.

Most Email clients expect an 'http://' to indicate a link and the link is terminated by the next space. It is very easy to:

1. Scan a text email for links

2. Isolate the link text

3. Scan inside the link for another URL

4. If one is found convert it to a warning and disable the double link.

e.g. for Eudora on Windows a DLL plugin written to perform these steps is an almost trivial exercise.

Similarly for other email clients.

Similarly for browsers.
