Are you sure? The only comment spam I've seen on LJ has been from anonymous users, not registered users. And up until very recently, it was possible for registered users to post without needing a validated email address. That's changed only recently.
Although looking at the Recent Posts feed, there are some spam posts, yes. Not nearly as many, though.
