I am just commenting on how it wouldn't be good if moderated topics could be converted to self-moderated ones. I am not implying that you are wrong in anyway, but what I would have done, that's why I used the word 'self-centered' for myself. Other members can be self-centered, change moderated thread to self-moderated thread and delete some replies that is not satisfying the topic creator. What can be right that's worth no deletion can be deleted wrongly. So, if a topic is self-moderated, people would have known right from the start to either post there or not.
