The link doesn't work because he cut and pasted it from another forum post, rather than from his website. When you post a long link in the forum, it shortens the displayed link by inserting periods and removing letters - but the HTML behind the link it creates still points to the right place.
If you cut and paste the text, it only copies the displayed text, i.e. the shorter version of the URL. You need to right click and select "Copy Link URL" or similar.
Or, you could just take this as a hint that you've been spamming too long...
