High Rankings Advisor: Hijacked Site or Google Mistake?

Here's a friday teaser for you - what on earth is going on here?

am the Webmaster for seasidegolf.com. We have been number one or two in Google for our keyword phrase for almost 3 years now.

I checked Google today and to my surprise someone copied my entire web

site and the link from Google to my site is now pointing to this person's stolen version of my site. I followed the links and found my entire site recreated, each image copied from my server and put onto theirs.

The best guess so far as to what might have happened comes from Ralph Tegtmeier, aka Fantomaster:

It's most probably a Google issue. We've seen this before when Google pointed to an old, expired domain that wasn't active anymore, redirecting visitors to another, entirely unrelated one.

I'm not sure that I buy that as it just seems to coincidental that the redirect came into play at the same time as the guy's site gets copied. Any ideas?
