How can Google crawl a private forum?

I know of a forum that has been crawled for over a year now and 99% of their forum is private, you have to register in order to view their content. But you can still see some cached content form google....

How can I do this?

As in your other thread, this is called cloaking and is not allowed by Google, et al.
