Turns out I was right and the .htaccess file was blocking the crawlers. Alcar has fixed it and Google can now see us. Now we just have to wait for them to update their search databases.

EDIT: A look at the 'Who's Online' tells me that there are a lot of guests checking out random threads. That looks like some crawler behaviour to me.

Also, I never noticed it before, but those exclamation mark icons in the attached image tell me that those guests attempting to register accounts are getting an error message. I was initially worried, but then I checked their IP addresses and every one is a known spammer. That means that our automatic spambot detection is working!
