Site Guardian's initial focus is blocking bad referrers. nukeSPAM block user registration by known spammers.
Not sure of Guardian's future plans for Site Guardian, but I am interested in adding Akismet or other content filtering to comments, forum posts, etc. That said, using a comment system like Disqus, which already has that built-in (and in already integrated with Tricked Out News), might be all we need...
