Can Forumosa disclose your identity to the authorities?

We’ve gone over some of this before

Legality Question Regarding Forums

I’m interested. Suppose someone said that so-and-so is a horrible fuckhead, here, could the coppers/lawyers demand that you give up their IRL identities? What happens if you say that a restaurant is rubbish and they want to sue you? Is admin obliged by law to give up their real names or ISP addresses? I’ve seen bloggers getting sued for bad restaurant reviews,so just wondering if this site protects its users from similar.
