it definitely means Jeff and Malice are off the hook. It actually makes each individual poster responsible for what their posts.

If a post is actionable or not is another thing entirely.

For instance, typing "jrv you are a snake in the grass I wish you would die" is clearly not actionable. Typing Marc Wallaces premature obit is not actionable. Posting publicly that a particular poster sends you hate mail and child porn just might be actionable.
