It’s a web redirect AJ put together, the site it leads you to is this one, just for some reason the redirect continues to display “Shandorfans.com” instead of “GBFans.com”.
It’s an alias but it’s missing the redirect. Definitely worth fixing because (as well as potentially confusing users) it means duplicate results in Google, which will hurt GBFans’ search engine rankings (he will be penalised for duplicate content by Google’s algorithm).
Should be possible to add a redirect condition which matches any domain except the primary one, it looks like there’s about 10-15 other alias domains sitting on this hosting account (based on the SSL cert).
