I just tried it and got the same page as you did. I have had this happen to my web site. Someone hacked into the web server that hosted my web site and put all kinds of spam pages and other stuff in it. The hacker wasn't looking for my site specifically but hacked the web server. Luckily I had a backup and was able to restore my files. I also changed my password.
AM Hobbies will have to follow the "Webmaster Tools" link on that page to clear his site with Google.
