Community moderation just won't work with Facebook - the whole point of FB is that it's gated communities. Your options are to only moderate the public areas (which may catch some, but not the vast majority of the content they are talking about here), allow moderators to access private areas (which leads to invasion of privacy that is a different problem - imagine the "strangers can sign up for moderation and see your private stuff!" headlines), or only allow moderation over content they can see, which means not catching this kind of stuff, as the only people in those communities are a part of it (or investagative journalists, I guess).
