Your first point is a good one, and looking back was presumably the basis for pg's disagreement. And as long as there is no serious problem with posts by brand new accounts that alone is likely a good enough reason to say I'm wrong. Your second point could be fixed by allowing users to create pseudo-accounts that don't visibly link back to their main accounts. Although as I think about that now that would only work until lawyers got involved, so not at all on serious issues. On second thought I concede to your points.
