The feedback forum is here to help us figure out what areas of the site need to be improved, and how our moderators are doing managing it. We don't generally care about feedback regarding other users - we're not really responsible for them, and the feedback won't help us improve anything.
Although I understand that the thread about Unb4nn3d was written with the intention of encouraging a promotion, the fact is, until he is a on our staff, his activity is not officially our concern. And, since we don't allow "you should promote..." threads, I can sort of see why it was removed.
